Recent advances in high mobility donor–acceptor semiconducting polymers
In this Highlight, we present the most recent work on solution processable high mobility donor–acceptor type polymers. We discuss the approaches that have been taken to improve both hole (and electron) mobility further. We will not only focus on chemical design criteria, but also describe certain processing approaches which have led to impressive hole mobilities of up to 5.5 cm2/Vs.

Multi length scale porosity as a playground for organic thermoelectric applications
Porous conducting polymers are intriguing heat harvester candidates. This review focuses on the different strategies to vary the porosity range (from micro- to macro-pores) and their impact on thermoelectric properties.

Tailoring the 3D porous structure of conducting PEDOT:PSS gels via ice-templating
Well-controlled gelation of fibrillar PEDOT:PSS and growth of ice crystals yield robust anisotropic macroporous materials with a tuned pore size. The honey-comb like structure is at the origin of the low thermal conductivity.

High thermal conductivity states and enhanced figure of merit in aligned polymer thermoelectric materials
Control of morphology and chain alignment in polymer thermoelectric materials is critical to their performance. A x25 improvement in zT is reported for chain aligned films.

Original polymorphism in a naphthalene bisimide π-conjugated organogelator: a complex interplay between hydrogen bonding and heterocycle π-stacking
A naphthalene bisimide organogelator forms different supramolecular assemblies in the gel phase and in the solid states; the structures of these different polymorphs have been uncovered by electron and X-ray diffraction, UV and FTIR spectroscopies.

Reversible J- to H-aggregate transformation in thin films of a perylenebisimide organogelator
A perylene bisimide organogelator is shown to behave as a reversible stimuli responsive material: thermal annealing and contact with organic non solvents allow to switch back and forth between a green J-type (Form I) and a red H-type (Form II) aggregate in thin films and powders of a N,N′-substituted H-bonding perylenebisimide (PBI-C10).

About this collection
The Journal of Materials Chemistry annual lectureship, established in 2010, honours early-career scientists who have made a significant contribution to the field of materials chemistry.
Dr Jovana Milić (University of Fribourg, Switzerland) is the recipient of the 2023 Journal of Materials Chemistry Lectureship. We have also recognised two outstanding runners-up, Dr Kwabena Bediako (University of California, Berkeley, USA) and Dr Laure Biniek (Institut Charles Sadron, CNRS – Strasbourg, France).
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, we have decided to additionally recognise runners-up for the Journal of Materials Chemistry Lectureship.
To celebrate, we have collated some of Kwabena and Laure’s publications in Royal Society of Chemistry journals in this 2023 Lectureship runners-up web collection.
