Boroles get a stability boost

Anisha Ratan writes about a hot Chemical Science article for Chemistry World

Scientists from Germany have reported a breakthrough in borole stability, using bulky fluoromesityl groups, which could help these anti-aromatic molecules realise their potential in optoelectronic devices.

Boroles are heterocycles with a 4π-electron BC4 ring and subsequent electron-accepting abilities. This makes them great candidates for electron-transporting and accepting materials in organic light-emitting diodes and photovoltaics. Read the full article in Chemistry World»

Photoredox catalysis mechanisms seen in new light

Richard Massey writes about a hot Chemical Science article for Chemistry World

A debate over whether photoredox-catalysed reactions proceed via chain processes may now be settled, thanks to new mechanistic insight brought to light by scientists in the US. The research, led by Tehshik Yoon at the University of Wisconsin–Madison, shows that commonly used light/dark experiments can result in mechanistic misdiagnosis.

Whilst interest in photoredox catalysis has recently burgeoned – the reactions are used in natural product and pharmaceutical synthesis – our understanding of their mechanisms hasn’t kept pace. In particular, the extent to which the reactions involve chain processes is not fully understood, leading to conflicting explanations. Several groups have reported that the final product-generating step proceeds only by reduction of the radical cation product by the reduced photocatalyst in a closed catalytic cycle, whilst others have reported that the product is formed by an additional chain propagation step involving another equivalent of substrate.

Smaller, better chemosensing porous polymers

Researchers from the CSIR–National Chemical Laboratory have demonstrated that upon exfoliation of an imide-based covalent organic framework to its nanosheet counterpart, its ability to detect the presence of nitroaromatices is dramatically enhanced.

The exploitation of porous frameworks, both metal-organic and wholly organic in nature, for their ability to take up and store gases and small molecules, has been well reported over the past few decades. The modularity of these frameworks with respect to their size, flexibility and chemical functionality gives rise to their propensity to adsorb a myriad of chemicals; however, this process is not always selective and the chemical instability of these frameworks can cause difficulties in their extension towards real-life applications. A framework that a) is able to favourably and preferentially adsorb chemicals with high sensitivity, and b) exhibits chemical stability under a wide range of conditions, remains somewhat elusive and is thus a hot topic of investigation in many research groups.

Whilst the uptake and sensing properties of two-dimensional porous polymers have been well studied, the bulk nature of these materials often results in the decrease of their properties on account of the extensive aggregation of the polymer layers and resulting reduction of electrons available to interact with guest molecules. Rahul Banerjee and researchers from the Council of Scientific and Industrial Research – National Chemical Laboratory set out to address this limitation in the field of porous polymers through the Liquid Phase Exfoliation of an imide-based covalent organic framework to its covalent organic nanosheet (CON) analogue. Such a CON, which contains between five and fifteen layers of the material, has chemical and thermal stability equal to that of its bulk counterpart; however, its sensing ability down to 10–5 M towards 2,4,6-trinitrophenol (TNP) and other nitroaromatic explosive chemicals is far superior. Furthermore, this reversible detection upon uptake can be seen both spectroscopically in solution and visually in the solid state via the turning off and on of the CON luminescence respectively.

The ability to quickly and selectively detect chemicals is of paramount interest to researchers worldwide, particularly those chemicals that pose a threat to societal health and safety. The methodology involving covalent organic nanosheets developed in this research offers a new approach to and a first step towards increasing the selectivity and sensitivity of detection by porous frameworks for chemicals, in this case nitroaromatics like TNT.

Insights on a high performing MOF

Victoria Richards highlights a recent Chemical Science Perspective article looking at HKUST-1

Metal-organic frameworks (MOFs) have received over a decade’s worth of attention from scientists worldwide. These porous materials can be constructed from almost an infinite combination of organic ligands and metal ions, which has spurred scientists to become creative in their designs, delivering materials with a wide range of useful applications.

In this recently published Chemical Science Perspective, Christopher Hendon and Aron Walsh (recently announced as the winner of the 2015 Chemical Society Reviews Emerging Investigator Lectureship) provide unique insight on the importance of the electronic, magnetic and physical properties of MOFs, focusing their attention on the body of evidence available on HKUST-1.

Many of the most successful MOFs contain arrays of copper paddle wheel motifs, and HKUST-1 is no exception. First reported by Williams in 19991, HKUST-1 remains one of the most high-performing materials of its kind and, thanks to it being high in demand, is one of few commercially available MOFs on the market.

With fresh analysis in hand, this report provides researchers with key design principles for the construction of MOFs with tailored chemical and electronic properties, potentially furthering the high-performance applications of these materials.

Professor Shankar Balasubramanian gives the opening talk at ISACS 16

From 15-18th June, the lecture theatre at ETH Zurich was almost full as delegates from 26 different countries gathered to hear the latest research in the field of Chemical Biology as we continued our series of International Symposia on Advancing the Chemical Sciences.

Across the 4 days of the conference we were treated to a diverse range of topics, from the very beginnings of life as we know it with John Sutherland to the latest diagnostic markers in various stages of clinical trials with Annette Beck-Sickinger, Yasuteru Urano and others. We also enjoyed various contributions on the latest synthetic developments to smooth the process of discoveries and heard about the latest natural product being identified and their potential applications.

We were delighted to have an enthusiatic participation in our “flash” poster presentations (just three minutes each) and overall around 80 posters were displayed and discussed during the event.

The Chemical Science sponsored poster prize was won by Eugenio Indrigo (University of Edinburgh) for his poster on “Palladium mediated chemistry in living cells, while the Chemistry World poster prize (and associated mug!) was won by Oliver ThornSeshold (Ludwig-Maximilians-Universität, Munich). Congratulations to them both!
