Alkylated Dinaphtho[2,3‐<i>b</i>:2′,3′‐<i>f</i>]Thieno[3,2‐b]Thiophenes (C_<i>n</i>‐DNTTs): Organic Semiconductors for High‐Performance Thin‐Film Transistors

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 Cn-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 cm2 V−1 s−1 and Ion/Ioff > 108.
