Thiophene-based bent-shaped luminescent liquid crystals: synthesis and characterisation

open access: yes, 2017
Five new bent-shaped compounds based on the 2,5-disubstituted thiophene central core were successfully synthesised. The lengths of the rigid centres as well as the degree of conjugation were varied by coupling benzene, naphthalene and biphenyl systems to

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
