Paper in Angewandte Chemie, with a pinch of salt!

Fantastic news! A paper from the Faul Research Group by Jie Chen (now back in China), Esther Townsend (BCFN), Veronica del Angel Hernandez, Pan, and colleagues from the Xi’an Jiaotong University in China appeared in Angewandte Chemie today!

The discovery of the Bristol-Xi’an Jiaotong (BXJ) approach, where we use simple inorganic salts to carefully tune N-containing conjugated microporous materials (CMPs), enables elegant synthetic control over the surface area, pore size distributions and function of N-containing CMPs. This approach enables the preparation of amorphous porous materials that start to challenge COFs and MOFs in properties and function!

Well done to all involved!!

It has been a while …

… since our last post! Apologies! Lots have been happening since the end of March, with Charl teaching at Tsinghua, visiting Jilin and attending the UoB’s graduation ceremony (see the video here!).

In addition, Basiram has joined the group as new PhD student, and Sebastien has joined as independent research fellow, with several more visitors arriving over the summer! And, as always, someone will be leaving – this time Maciek, who will be taking up an independent academic position in Bath (congrats!).

And, finally, we hope to have some good news on some big publications very soon! More news, updates and pictures to follow soon!

Starting the year on a high note – first publication!

Happy 2019! The year has started on a high note, with our first paper (joint with our collaborators Jiangfei Xu and Xi Zhang from the Department of Chemistry at Tsinghua) just accepted and appeared online in Chemistry Society Reviews!

Henry and Charl contributed to the tutorial review, entitled “Molecular Engineering of Polymeric Supra-amphiphiles“, where the concept of supra-amphiphiles is introduced and discussed in detail! Well done to all involved!

Djen’s paper published online!

Djen’s paper appeared online today on the Advanced Materials Technologies website!

A major challenge for soft electroactive devices such as dielectric elastomers is the fabrication of thin, precisely patterned, stretchable conductors. In this work, laser‐scribed graphene oxide is used to fabricate intricate, stretchable electrodes for dielectric elastomer actuators.

The method is simple, low‐cost, and green (free of organic solvents) and produces arbitrary geometries with 0.1 mm resolution.

 

And now Ben’s paper – accepted and published online!

It has been a great week for publications! Ben’s paper was recently accepted, and just appeared earlier today on the MSDE (Molecular Systems Design & Engineering) website! This study, entitled “Tipping the polaron–bipolaron balance: concentration and spin effects in doped oligo(aniline)s observed by UV-vis-NIR and TD DFT” is an invited contribution to the special themed collection “Soft Materials Nanoarchitectonics”.

We describe a robust computational protocol for modelling the molecular geometries, electronic structures and absorption spectra of oligomers of the widely-used and versatile conducting polymer, poly(aniline). By comparing experimental UV-vis-NIR and EPR spectra with TD-DFT simulations, we discovered it is possible to switch reversibly between diamagnetic and paramagnetic forms (bipolaronic and polaronic states) of oligo(aniline)s in solution simply by adjusting dopant concentrations – a finding which could reinvigorate research into conduction mechanisms in poly(aniline) and related materials, as well as allowing control of material properties and functionality.

Well done Ben, Shao, Steph, and collaborators Dave, Patrice and Natalie!

Djen’s paper accepted!

Great news – Djen’s paper on “Laser-scribed Graphene Oxide Electrodes for Soft Electroactive Devices” has been accepted for publication by Advanced Materials Technologies.

Here we (Djen, Jonathan Rossiter and Charl) show that laser-scribed graphene oxide (LSGO) can be used to fabricate patterned, stretchable electrodes for dielectric actuators (DEAs) – even an actuating University of Bristol logo!

Well done Djen!

Another joint Manners/Faul paper!

Charlie, who was a joint Manners/Faul student (and now in Toronto), just had a full paper accepted in Chemistry European Journal! He had helped from Henry, from the Faul group, Xiaoming, former Manners group postdoc and Rob from the EM unit.

In this paper we show controlled solution self-assembly of an amphiphilic perylene diimide by a seeded-growth mechanism, to form colloidally stable, one-dimensional fibres with controllable lengths and low dispersities under kinetic control. Well done to all involved!
