| 摘 要： | 1 Results In recent years,interests in organic semiconductor have increased due to the applications in optoelectronic devices such as organic light-emitting diodes (OLEDs)[1],field-effect transistors (FETs)[2],and photovoltaic devices[3]. These organic electronics have several advantages over conventional inorganic electronics including facile processability,chemical tunability,compatibility with plastic substrates,and low cost to fabricate. Selenophene-based molecules show good π-conjugating electron overlap between adjacent molecules,because they have high electron density and stronger electron-donation property than thiophene moieties. Therefore selenophene-based molecules have recently received significant attention in the research field of organic FETs.
