Melt-processing of conjugated liquid crystals: A simple route to fabricate OFETs

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.
