We have demonstrated an efficient one-step synthesis of pyrene end-capped thiophene oligomers as active materials for organic thin-film transistors (OTFTs) and donor materials for organic solar cells (OSCs). In particular, the OTFT device based on 5,5 ''-di(pyren-1-yl)-2,2':5',2 ''-terthiophene (3s) exhibited a reasonable field effect mobility of 0.11 cm(2) V (1) s (1), and a power conversion efficiency of 1.20% was achieved when 3s was used as active materials in OSCs. These pyrene end-capped thiophene oligomers are considered to be good organic semiconducting materials for OTFTs and OSCs.
