Melt‐Processing of Conjugated Liquid Crystals: A Simple Route to Fabricate OFETs

Abstract

Melt-processing of 5,5′-bis(4-hexylphenyl)-2,2′-bithiophene leads to a favorable morphology of the conjugated liquid crystal in the channel of an OFET (see figure) and a fivefold improvement of the mobility over that found for conventional devices fabricated by evaporation. This process does not require solvents or vacuum-deposition processes.
