Paper Abstract

High performance n-type FETs have been accomplished by using novel heterocyclic systems with trifluoromethylphenyl groups. To enhance intermolecular interactions, selenophene rings were introduced. Some FET devices showed higher electron mobilities than 0.1 cm2V-1s-1. The mobilities of the selenophene-containing materials were higher than those of the corresponding thiophene analogues. The relationship between the structures and FET characteristics have been investigated. The threshold voltages were reduced by introducing heterocyclic units with higher electron affinity.
