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!

University of Rennes1, France

Charl was invited, as visiting professor, to spend a few days at the University of Rennes1 by former postdoc Dr Franck Camerel. Franck, who is in the MaCSE (Matière Condensée et Systèmes Electroactifs) group,

Several days of excellent and stimulating scientific discussions were closely accompanied by good food, and the pleasure of seeing old friends again! Thank you Franck!

Back in Beijing!

Charl joined an international panel of experts to help with the external evaluation of the School of Chemistry and Chemical Engineering at BIT (Beijing Institute of Technology). The evaluation ended with a series of scientific seminars by some panel members, including Prof. Donglin Jiang (now at NUS, Singapore), and Charl!

Here Donglin and Charl are in discussion after Donglin’s impressive talk!


Crazy conference season in China!

Charl has just completed a short, but busy, trip: after visiting Shu-Hong’s labs, an additional visit to the Hefei University of Technology, the International Conference on Energy and Environmental Materials (all in Hefei), and then the International Seminar on Advanced Materials (in Shanghai)!

As the latter was held at Donghua University, Charl had the chance to catch up with former postdoc Yaozu (now professor at Donghua), who also attended the conference. Charl also managed to visit a small company in Anji, a smaller city close to Hangzhou – busy time indeed!

Visiting Shu-Hong at USTC, Hefei

It has been more than 10 years since Charl’s last visit to Hefei, where Shu-Hong Yu is based at the University of Science and Technology (USTC). It was great to visit his very productive laboratories, doing very impressive science, whilst also giving a talk and discussing new collaborative opportunities!

Great to catch up with old friends again – thanks for a great visit!

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!



Visitor from Monash!

Luke Giles, PhD student from our collaborator Dr Rico Tabor (leading the SMaC Lab at  the School of Chemistry at Monash) and co-supervised by Charl, visited our labs recently. Rico, who did his PhD at Bristol (and spent some time working in the FRG labs) is a regular visitor – it is great to now expand our interactions with Luke’s visit (as he travels around Europe).

Here Luke is with some of the FRG members before heading out back to Melbourne again! Looking forward to the next visit!
