Abstract

Abstract: Synthesis and characterization of 2,5-bis(2-phenanthrenyl)-thieno[3,2-b]thiophene(PhTT) were reported. The compound exhibits a great thermal stability. Absorption measurements and electrochemical characterization revealed that PhTT has a relative broad bandgap and low HOMO(the highest occupied molecular orbital) level. The field-effect mobility(μ_FET) of PhTT from top-contact thin film transistors was 0.021 cm²/(V·s). The thin film transistors of PhTT show a good environmental stability.

Key words: Phenanthrene, Thieno[3,2-b]thiophene, Organic semiconductors, Thin film transistors(TFTs)
