Abstract

A series of alkylated dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b] thiophenes (Cn-DNTTs) were developed as vapor-processable organic semiconductors for organic thin-film transistors (OTFTs). All the C n-DNTT-based OTFTs showed typical p-channel FET characteristics and among them, C10-DNTT possessing two n-decyl groups gave excellent FET characteristics under the ambient conditions with mobility close to 8.0 cm 2 V-1 s-1 and Ion/Ioff > 108.
