A novel calamitic mesophase semiconductor with the fastest mobility of charged carriers: 1,4-di(5′-octyl-2′-thienyl)benzene

Abstract

The carrier mobility of highly ordered lamellar mesophases was evaluated by a Time-of-Flight (TOF) method for mesogenic 1,4-di(5'-octyl-2'-thienyl)benzene (8-TPT-8) to reveal the fastest drift mobility (0.1 cm(2) V(-1) s(-1) for the lowest temperature mesophase) in calamitic liquid crystals reported to date.
