Abstract: Abstract Direct arylation polymerization enables “greener” synthesis of a high-performance semicrystalline π-conjugated polymer, poly[(2,5-bis(2-hexyldecyloxy)phenylene)-alt-(5,6-difluoro-4,7-di(thiophene-2-yl)benzo[c][1,2,5]thiadiazole) (PPDT2FBT). The resulting polymers show a hole mobility of 4.7 × 10−3 cm2 V−1 s−1 in bottom-gate/top-contact field effect transistors, and a power conversion efficiency over… read more here.

Abstract: Dioxyheterocycles, particularly 3,4-ethylenedioxythiophene (EDOT), have proven to be useful building blocks for conjugated materials targeting various applications. The 3,4-phenylenedioxythiophene (PheDOT) unit is similar to the EDOT unit in terms of planarity and steric interactions, but… read more here.
