A series of thiazolothiazole-phenylene co-oligomers was synthesized and their properties, particularly as semiconductors for OFETs, were investigated. The naphthyl and biphenyl- substituted derivatives showed p-type semiconducting behavior with hole mobilities ranging from 10-2 to 10-1 cm2 V-1 s-1. The hole mobility and on/off ratio were enhanced to 0.12 cm2 V-1 s-1 and 10 6 on the HMDS treated substrate. The introduction of phenyl groups as end substituents was found to be favorable for charge transport and air-stability. The Royal Society of Chemistry 2007.
