Pathways to increase the dissymmetry in the interaction of chiral light and chiral molecules

This perspective explores the dissymmetric interaction between circularly polarised (CP) light and chiral molecules. Such interactions are central to many applications from next generation displays to asymmetric photochemical synthesis.

Concepts and principles of self-n-doping in perylene diimide chromophores for applications in biochemistry, energy harvesting, energy storage, and catalysis

Self-doping is an essential method of increasing carrier concentrations in organic electronics that eliminates the need to tailor host—dopant miscibility, a necessary step when employing molecular dopants.

On the factors influencing the chiroptical response of conjugated polymer thin films

We study the influence of the physical and chemical structure on the chiroptical response of fluorene-based polymeric systems and reveal the significance of electric-magnetic coupling, at both short and intermediate length scales on the magnitude of the dissymmetry.

Polaron stability in semiconducting polymer neat films

We describe a spectroelectrochemical approach to accelerated electrochemical stability studies of conjugated polymers under oxidative stress. The polaron stabilities of alternating copolymers based on (i) thiophene and thiazole, namely PTTz, and (ii) bithiophene and thiazole, namely PTTTz, are compared in neat films with that of P3HT. P3HT is found to be the most stable whilst PTTz is found to be the least stable.

We are delighted to announce that Professor Sahika Inal has been selected as the winner of the Journal of Materials Chemistry Lectureship 2022. This year we are also pleased to celebrate two runners-up, Jessica Wade and Luisa Whittaker-Brooks!

Each year we have a large number of excellent researchers nominated for the lectureship award across Journal of Materials Chemistry A, B and C. To recognise the diversity of the three journals, overall community and candidates nominated each year, going forward we have decided to additionally recognise runners-up for the Journal of Materials Chemistry lectureship.

To celebrate, we have put together this collection of Jessica and Luisa’s publications in Royal Society of Chemistry journals. We hope you enjoy reading this collection of fantastic research from our Journal of Materials Chemistry lectureship runners-up! You can learn more about Jess and Luisa on our blog.
