通过Sonogashira偶联反应合成了一种新的以芘为核的p-共轭分子。单晶微带基FET的迁移率最高，为0.7cm（2）V（-1）s（-1）（I（on）/I（off）> 10（6））。采用单晶微带在极低光强（I = 5.6 μ W·cm ~（-2））下在有机光电晶体管（OPT）中工作。
A new pyrene-cored p-conjugated molecule has been synthesized through Sonogashira coupling reaction. The single-crystalline microribbon-based FET exhibited the highest mobility of 0.7 cm(2) V(-1) s(-1) (I(on)/I(off) > 10(6)). Single-crystalline microribbons were employed to operate in an organic phototransistor (OPT) under very low light intensity (I = 5.6 mu W cm(-2)).
