摘要：

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) cm(2) V-1 s(-1). The hole mobility and on/off ratio were enhanced to 0.12 cm(2) 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.
