Abstract:	摘要： Three benzo[d,d′]thieno[3,2-b;4,5-b′]dithiophene (BTDT) derivatives, end-functionalized with benzothiophenyl (BT-BTDT; 2), benzothieno[3,2-b]thiophenyl (BTT-BTDT; 3), and benzo[d,d′]thieno[3,2-b;4,5-b′]dithiophenyl (BBTDT; 4), were prepared for bottom-contact/bottom-gate organic thin-film transistors (OTFTs). An improved one-pot [2 + 1 + 1] synthetic method of BTDT with improved synthetic yield was achieved, which enabled the efficient realization of new BTDT-based semiconductors. All of the BTDT compounds exhibited high performance p-channel characteristics with carrier mobilities as high as 0.34 cm2/(V s) and a current on/off ratio of 1 × 107, as well as enhanced ambient stability. The device characteristics have been correlated with the film morphologies and microstructures of the corresponding compounds. 其他題名： ACS Appl. Mater.
