“NO sorption, in-crystal nitrite and nitrate production with arylamine oxidation in gas–solid single crystal to single crystal reactions” by Christine J. McKenzie et al., as chosen by Penny Brothers:

This year marks 100 years since Alfred Werner’s death in 1919, and it is over a century since he won the 2013 Nobel prize for developing the conceptual framework that we now understand as coordination chemistry. Studies on cobalt complexes formed the cornerstone of Werner’s work, and this paper shows they are still relevant and important well into the 21^st century, although with some surprising twists. Single crystals of tetranuclear Co(II) and Co(III) complexes chemisorb nitric oxide (NO) which, after exposure to O₂ physisorbed from air, is transformed to nitrite, nitrate and an aryl nitro group in remarkable single crystal to single crystal reactions. The medical and biological significance of NO and the solventless redox chemistry all occurring in the crystalline phase suggest exciting possibilities for its highly selective capture and conversion.

“Imidazolium-benzimidazolates as convenient sources of donor-functionalised normal and abnormal N-heterocyclic carbenes” by Ulrich Siemeling et al., as chosen by Manfred Scheer:

Mesomeric betaines are related to N-heterocyclic carbenes because of their interconversion by tautomerisation and therefore can act as “instant carbenes”. The authors established now imidazolium-benzimidazolates as a new and highly versatile “instant carbene” system. Depending on the steric demand of the imidazole N-substituent, normal but also abnormal NHC carbene coordination is observed. Thus, unstable but nevertheless highly interesting species are available starting from stable betainic precursors. Therefore, this paper contributes substantially to the chemistry of normal and abnormal N-heterocyclic carbenes.

Mechanical Stress Turns These Dendrimers Blue

12 Sep 2019

We all know what happens when materials take too much mechanical stress – they eventually break.

What if you could easily tell when something like a support was close to its maximum stress, before it undergoes a catastrophic event, just by looking at it? One option is to incorporate a mechanochromic polymer, a polymer that changes color when under sufficient mechanical stress, to provide a visual indicator that a material has reached a specific stress threshold. The polymers don’t need to be entirely composed of mechanochromically active moieties to exhibit useful properties; many studies have focused on a single active mechanophore at the center of a large polymer chain. In fact, the mechanical force is greatest at the center of a chain and is directly proportional to the length of the chains. This holds for polymers in solution but hasn’t been extensively studied in the types of bulk systems useful for applications.

Recently, researchers in Japan set out to characterize the effects of chain length and branching on mechanochromic dendrimers, polymers with monodisperse and regularly branched globular structures. Showing that dendrimers exhibit mechanochromism is already a novel result, but their well-defined nature allowed the researchers to draw correlations between structure and bulk responsiveness. They employed diarylbibenzylfuranone (DABBF) as the mechanochromic moiety since it generates arylbenzofuranone (ABF) radicals, which are blue, air-stable, and electron paramagnetic resonance spectroscopy (EPR) active, when exposed to mechanical force (Figure 1).

Figure 1. Structure of the DABBF moiety and the active ABF radicals generated by its dissociation.

These characteristics allow for straightforward qualitative and quantitative analysis. The team coupled the DABBF moiety with two series of dendrimers, with increasing generations having larger and more highly branched monomer units, to create a range of molecular weights and degrees of branching for study. The dendrimers showed a color change from white to blue (Figure 2) when ground in a ball mill, which was used to ensure the reproducibility of the force applied to all samples.

Figure 2. Photographs of the first (top) and second (bottom) mechanochromic dendrimers before and after grinding, showing the color change associated with the generation of ABF radicals.

EPR measurements confirmed the presence of the ABF radicals in the samples after milling, demonstrating that the color change is due to the cleavage of the DABBF. The integrated EPR spectra were used to quantitatively determine the percentage of DABBF moieties that dissociated. The responsiveness of the dendrimers increased exponentially with increasing generation and branching. However, the primary factor governing ABF generation was found to be molecular weight. Two dendrimers with different levels of chain entanglement, but similar molecular weights, exhibited comparable cleavage ratios. The question then became does molecular weight increase the transfer efficiency of force to the DABBF or does the increased steric bulk make it harder for the ABF radicals to recombine? To probe the kinetics of this process, the researchers varied the grinding time and saw that within 5 minutes all the highly branched samples reached their maximum dissociation level. Additionally, monitoring the ABF recombination showed that even after 6 hours approximately 95% of the radicals remained dissociated in all 3^rd and 4^th generation dendrimers. These data suggest that the enhancement in responsiveness can be attributed to better force transmission to the DABBF.

This work shows mechanoresponsiveness in a range of dendrimers with varying degrees of branching and rigidity. Not only did they demonstrate novel activity, but the researchers also probed the mechanism of the enhanced activity with increasing molecular weight. This initial study opens avenues to explore polymer rigidity, surface functionality, and other dendrimer features to design new, functional materials.

Synthesizing Polymers Using CO2

19 Aug 2019

Ring-opening polymerizations produce commercial polymeric materials including epoxy resins, but they usually liberate small molecules such as the greenhouse gas, CO₂. In the context of climate change, it is urgent to reduce CO₂ emissions. Recently, a group of UK researchers led by Prof. Charlotte K. Williams at the University of Oxford developed a step-growth polymerization method that self-consumed CO₂. The work has been published in a recent issue of Chemical Communications.

The synthesis involved two catalytic cycles (Figure 1). The first cycle polymerized _L-lactide-O-carboxyanhydride into poly(_L-lactide acid) (PLLA) via a ring-opening polymerization and released one CO₂ molecule per polymer repeat unit. In the second cycle, epoxide molecules (cyclohexeneoxide) combined with the CO₂ generated in the first step and grew into poly(cyclohexene carbonate) (PCHC) from the terminal ends of the PLLA chains. A di-zinc-alkoxide compound catalyzed both cycles and coupled the two processes together. The product is PLLA-b-PCHC block copolymers, which are composed of PLLA and PCHC covalently tethered together.

Figure 1. The two catalytic cycles are joined by a zinc-based catalyst, [LZn₂(OAc)₂]. The CO₂ gas produced in the first step serves as a reactant in the second step. OCA: O-carboxyanhydride; ROP: ring-opening polymerization; CHO: cyclohexeneoxide; ROCOP: ring-opening copolymerization.

The two reactions resulted in block copolymers with few byproducts. In-situ ¹H NMR revealed that the reactants in the first step (LLAOCA) were rapidly consumed during the first four hours (Step I, Figure 2a), and the concentration of PLLA increased notably. The concentration of PCHC only markedly increased after the concentration of PLLA saturated (Step II, Figure 2a). The byproduct of the second step, trans-cyclohexene carbonate, exhibited consistently low concentrations. The pronounced single peak in each size-exclusion chromatogram of the corresponding product confirmed the presence of block copolymers, instead of polymer mixtures (Figure 2b). Although the authors did not fully elucidate the origin of the excellent selectivity towards the block copolymer, they speculated that the change in CO₂ partial pressure played a role. Significantly, nearly all CO₂ molecules were consumed in the second step, with 91% incorporated into the block copolymer, and 9% converted to the byproduct.

The authors are investigating the detailed polymerization mechanism, as well as identifying new catalysts to expand the polymerization scheme to other polymers.

Targeting the Powerhouse of the Cell to Fight Cancer

17 Jun 2019

Everyone knows that cancer as a disease is awful, but the side effects of currently utilized chemotherapies have their own horrors. Research into natural products as therapies have found some promising compounds, but they face barriers to practical use in patients. One particular molecule, artesunate (ART), recently showed high potential for anticancer activity when in the presence of iron. Unfortunately, ART has major problems that limit its current applicability, including low solubility in water and high instability in biologically relevant conditions.

One approach to get around these issues is to encapsulate the drug (pun intended) in a nanoparticle-based carrier. A carrier with a hydrophobic interior and hydrophilic exterior can bring higher concentrations of drugs with low solubility into a cell and protect them from deleterious conditions in the body. An additional benefit is the relative ease of incorporating targeting ligands into the particles during synthesis. This allows the drugs to only interact with specific cells or, in this specific case, the mitochondria within cells.

Figure 1. Schematic of the nanoparticle synthesis process complete with targeting ligand molecules. The anticancer agent is activated in the presence of iron.

Researchers in China have prepared approximately 200 nm nanoparticle carriers for ART (Figure 1) using triphenyl phosphonium (TPP) as a mitochondrial targeting ligand. These nanoparticles remained stable in biologically relevant conditions for a week, sufficient for in-vitro studies. The studies showed significant decreases in cancer cell growth when the nanoparticles were used compared to the ART alone. The nanoparticles with TPP on the surface showed the highest efficacy, particularly when coupled with iron treatment to activate the ART.

Figure 2. Images of cells exposed to nanoparticles with (bottom) and without (top) a targeting ligand filled with different fluorescent dyes. The increased brightness corresponds to higher uptake of the nanoparticles by the cells.

To further investigate the cell uptake pathway of the nanoparticles, the researchers added fluorescent dye molecules to the inside of the particles. Once the cells took up and ruptured the nanoparticles, the dyes were released and became visible to the researchers (Figure 2). The fluorescence was twice as great in cells exposed to the nanoparticles treated with the TPP targeting ligand, showing its value for cell uptake. The researchers also used fluorescent dyes that react with reactive oxygen species (ROSs), as their generation is how ART kills cancer cells. The in-vitro studies showed an over three-fold increase in fluorescence from reactions with ROSs which, combined with data showing higher rates of cell death, supports the increased activity of ART when combined with this nanoparticle architecture.

Copper A3 Coupling using a Switchable Homogeneous/Heterogeneous Catalyst

06 Nov 2018

A MOC, I learned this week, is a metal-organic cage. I was familiar with MOMs, MOFs and MOBs, but MOCs were a new one. A MOM (metal-organic material) is a coordination-driven assembly constructed from metal nodes linked by organic ligands. MOMs encompass both MOFs (metal-organic frameworks) and MOCs (metal-organic cages). A MOF is an extended network with the potential for inner porosity, and a MOC is a discrete metal-ligand cluster. And that’s just about as far down the nomenclature rabbit hole I’m willing to go. If you’re keeping up you’ll realise that I forgot one! A MOB is a crowd of graduate students competing for free coffee at the public seminar.

Dong and co-workers at Shandong Normal University designed and prepared a MOM catalyst constructed from copper(II) nodes and a tripodal ligand consisting of a phenylic wheel functionalised with diketones. In chloroform these two components arrange into discrete MOC assemblies containing two tripodal ligands and three copper ions. The copper ions in the cluster are each coordinated to two diketone moieties (in a acetylacetonate-like fashion) in a quasi-square planar arrangement.

Synthesis of the tripodal ligand functionalised with diketone coordinating moieties.

An interesting property of the material is that it can switch between the MOC form, soluble in halogenated solvents, and an insoluble MOF that assembles upon addition of 1,4-dioxane. 1,4-Dioxane is both an anti-solvent and a ligand; coordination between copper and 1,4-dioxane binds the discrete MOC cages to each other, arranging them into the extended MOF structure. This behaviour can be exploited to prepare a practical catalyst that combines the benefits of both homogeneous and heterogeneous catalysis, namely that homogeneous catalysts are generally more efficient, selective and easier to study, but heterogeneous catalysis are easier to recover and recycle. What better way to solve this problem than with a catalyst that is homogeneous during the reaction conditions, but heterogeneous when it comes to product separation?

The authors used the A³ coupling reaction to demonstrate this concept in a catalytic reaction. The A³ reaction is a transition metal-catalysed, multi-component coupling reaction between aldehydes, alkynes and amines. The products are propargylamines, practical synthetic intermediates for the synthesis of nitrogen heterocycles. The A³ reaction has been extensively studied and can be effected by a wide range of transition metal catalysts. Its versatility makes it a popular choice as a model catalytic reaction to demonstrate innovative ideas in catalytic design – as the authors have done here.

Coordination-driven assemblies have a unique potential for the synthesis of differentially soluble materials, used by the authors for novel catalytic design. Whether this particular metal-ligand combination can be applied to other copper catalysed reactions remains to be seen, nevertheless the principle offers an innovative approach that augments the range of methods striving to bridge the gap between homogeneous and heterogeneous catalysis.
