Light and heat flip compound between phases

10 Jun 2016

By Charlotte Rowley.

Written by Tom Wilson for Chemistry World

Scientists from Japan can now transform an ionic liquid to a solid coordination polymer using UV light, and then reverse the switch using heat.

Tomoyuki Mochida and co-workers from Kobe University, Japan, synthesised a ruthenium-containing ionic liquid, which transforms to a yellow solid coordination polymer when irradiated with UV light. Applying heat reverses the process.

Secrets shown in a good light

10 Jun 2016

By Charlotte Rowley.

Written by Philippa Matthews for Chemistry World

Scientists in France have created paper that can carry secret messages. In visible light, the paper is indistinguishable from regular paper and users can read, write or erase messages using three different wavelengths of UV light.

The functionalised paper, made by François-Xavier Felpin from the University of Nantes, and colleagues, contains coumarin molecules attached to the paper’s cellulose fibres. Exposing the paper to UV light with a wavelength of 340nm causes coumarin to react and create cyclobutane dimers. These dimers are invisible under visible light, but fluoresce under a UV lamp.

Sunset for perovskites?

06 May 2016

By Bethany Johnson.

Hugh Cowley writes about a hot Chemical Science article for Chemistry World

Perovskites have arguably transformed solar energy more in the last few years than other technologies have in decades. But British researchers have called into question optimistic predictions of undiscovered perovskites.

Hybrid perovskites are a mix of organic and inorganic ions with the same crystal structure as calcium titanium oxide (CaTiO₃). Halide perovskites are a subset of these structures containing halide ions such as fluoride or chloride. Iodide perovskites such as methylammonium lead iodide (CH₃NH₃PbI₃) can convert sunlight to electricity.

Researchers use a decades-old geometric ‘tolerance factor’ to propose new combinations of ions that will form stable perovskites. Now, Robert Palgrave and his team at University College London, UK, have reassessed the validity of the tolerance factor in predicting new hybrid perovskite structures.

Iron-rich silicate plays cosmic matchmaker

05 May 2016

By Bethany Johnson.

Nelly Berg writes about a hot ChemComm article for Chemistry World

Computational chemists in Spain have discovered that iron in cosmic dust grains helps turn hydrogen atoms into molecular hydrogen (H₂).

The average density of the interstellar medium is several billion times less dense than even the best vacuum chambers on Earth. Collisions between hydrogen atoms are therefore rare, and when they do occur, only one out of every 100,000 creates H₂. Read the full article in Chemistry World»

Caging chemical weapons

14 Apr 2016

By Bethany Johnson.

Elisabeth Ratcliffe writes about a hot ChemComm article for Chemistry World

Scientists in the UK have developed supramolecular cages that can trap chemical weapon simulants using the hydrophobic effect.

Organophosphorous chemical weapons, such as sarin and soman, interfere with signals between nerve cells, and have recently been used to deadly effect in places such as Syria. Researchers are therefore trying to develop techniques that detect these chemical weapons in the environment, and destroy them. Read the full article in Chemistry World»

Macrocyle aromaticity switch is all about that base

12 Apr 2016

By Bethany Johnson.

Heather Powell writes about a hot ChemComm article for Chemistry World

Researchers have discovered a macrocyle that they can render aromatic, non-aromatic or anti-aromatic by altering the amount of base they add.

Meso-aryl expanded porphyrins are usually exceedingly twisted structures due to strong hydrogen bonds within them. Even though they contain many conjugated bonds, this twisted structure means that most of these porphyrins are non-aromatic (to be aromatic, a molecule not only needs conjugation, but must also be flat). Previously scientists had added hydrogen ions to disturb hydrogen bonding in porphyrins, causing them to untwist and become aromatic. Here, a team led by Dongho Kim from Yonsei University, Korea, have flattened a porphyrin by removing hydrogen ions. Read the full article in Chemistry World»

‘Lightning talk’ prize winner at the University of California Symposium for Chemical Sciences

08 Apr 2016

By Michaela Mühlberg.

Congratulations to our ChemComm ‘lightning talk’ prize winner at the University of California Symposium for the Chemical Sciences.

The meeting was supported by eight UC departments (UC Davis, UCLA, UC San Diego, UC Berkeley, UC Riverside, UC Santa Cruz, UC Irvine, UC Santa Barbara) representing all areas of chemistry including biological, organic, inorganic, analytical and physical chemistry. The symposium which was held for the first time provided an excellent opportunity for graduate students and postdocs to not only present their work in a multidisciplinary environment, but also take part in different workshops to further their career and establish connections with professionals from industry, government and alternative science jobs.

We would like to congratulate the winner of the best ‘lightning talk’, a short representation of the speaker’s research of about 5 min. The prize was given to Liban Saleh who is currenlty working as a Post-Doctoral Associate in the group of Alexander Spokoyny (UCLA). His research focuses on inorganic and organomimetic cluster chemistry towards functional materials.
