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

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 req...

Description
Summary: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.
