Abstract

A series of alkylated dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b] thiophenes (C_n-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 I_on/I_off > 10⁸.
