Hot Highlight: Porphyrinic metal organic frameworks

Three types of possible pillaring present in porphyrin paddlewheel frameworks using a 4,4'-bipyridine ligand

Metal-organic frameworks (MOFs) are a hot topic of research in crystal engineering given the range of potential applications, including catalysis, gas storage and sensing. The construction of the crystalline materials is very important to determine the properties of the material and this is controlled by careful selection of linkers (organic molecules) and joints (metal ions or clusters). 

Porphyrins provide a versatile choice of linker as they can accommodate a range of transition metals and main group elements, this allows metals to be introduced into the frameworks without the need for them to also act as joints, making the metal ions more accessible and increasing interaction with guest molecules. 

Schematic illustration of a metal–organic framework, assembled from metal nodes and metalloligands

Porphyrin based MOFs have been reported by Robson, Goldberg, Suslick, Li, Choe, Hupp, Ma and others, this Hot Highlight by Brandon Burnett, Paul Barron and Wonyoung Choe reviews the recent advances in porphyrinic MOFs, focussing on materials design, synthetic strategies and emerging applications.

March Crystal Clear: Crystal Snowflakes

This month’s Crystal Clear shows crystals which look remarkably like snowflakes!

FESEM image of dendritic PbTe nano-crystals

In fact this is an image of three-dimensional PbTe dendrites, taken using field emission scanning electron microscopy (FESEM). The paper, published in Issue 6 of CrystEngComm, details the fabrication of these crystals in the presence of β-cyclodextrin.

Gang Chen et al. of the Harbin Institute of Technology have developed a facile synthesis to control the morphology of the nano-crystals. Lead telluride is a typical IV–VI semiconductor and controlling the size and shape of the material has initiated substantial interest. Nano-cubes, nano-octahedrons, nano-wires, nano-rods and hopper crystals have been synthesised as well as flower-like and dendritic structures.

These dendritic crystals have been successfully synthesized via a facile, rapid solvothermal process in the presence of β-cyclodextrin. The authors have characterised the products and propose a mechanism of formation for the crystals and the influencing parameters.

To read more about their developments you can download the article now, which is free to access for 4 weeks.

February Crystal Clear: A Clear Crystal

This month’s crystal clear could almost be an ice cube, it’s certainly large enough!

In fact this is a single crystal of K3B6O10Cl synthesised by Shilie Pan et al. and has dimensions of 25 x 11 x 7 mm3. The team based at Xinjiang Technical Institute of Physics & Chemistry have published their findings in Issue 3 of CrystEngComm, detailing the growth of these crystals as well as their optical properties.

Materials which possess non-linear optical (NLO) properties are of great interest given their potential applications in photonics, including optical storage and frequency mixing. Using a top-seeded solution growth method the team synthesised these large crystals and found them to have a high laser damage threshold and a wide transparency range. The K3B6O10Cl crystals are potentially promising in high-power UV light generation.

It is important for application that very high quality single crystals are formed; initially the researchers found that spontaneous nucleation and crack formation hindered quality crystal growth, with crystalline grains floating on the solution surface and attaching to the edge of the growing crystal.

To see how the team overcame these problems to produce the beautiful single crystal displayed here you can download their article now, which has been made free to access for 4 weeks.

IUPAC Update: Coordination polymer/MOF nomenclature

Following on from the previous blog last year ‘IUPAC Survey: Coordination polymer/MOF nomenclature’, we can now report the IUPAC division of Inorganic Chemistry has published a Highlight article ‘Coordination polymers, metal–organic frameworks and the need for terminology guidelines’. The paper is a summary of the work of the task group so far and the interactions they have had with scientists in the area.

The most common terms are coordination polymer and metal-organic framework and it can be difficult to know which structures are covered by which names and what these names mean to different people. This paper introduces the different ideas between various groups and provides an agenda for further work in the area.

Given the significance and interest of this article it has been made free to access until the end of March and can be downloaded below.

Influential Intermolecular Interactions

The crystal structures and packing of organic compounds in the solid state are determined by the types of bonds between the molecules, the structure will depend upon the number, strength and orientation of inter-molecular interactions and bonds. Piyush Panini and Deepak Chopra of IISER Bhopal looked to investigate this further by synthesising, characterising and crystallising a series of 10 isomeric mono and di-trifluoromethylated benzanilides.

 

 

While the traditional C–H  –  –  –  O/N type hydrogen bonds are well studied it is more difficult to evaluate some of the weaker interactions, such as those involving halogens. In this Hot Article the authors look to link the cooperative effects of some of the weaker interactions to crystal structures and packing motifs, making some interesting discoveries.

All hot articles are free to access in CrystEngComm for 4 weeks, so you can download this article for free until next month by clicking the link below.
