摘要
Three new solution-processable tetrabutylanthradithiophene (TBADT)-based organic semiconductors bearing two phenylethynyl, thiophen-2-ylethynyl, and thieno[3,2-b] thiophen-5-ylethynyl substituents have been synthesized and their thermal, optical, and electrochemical properties have been characterized. Preliminary tests of these compounds via drop-casting for thin-film transistors showed p-channel TFT transport with hole mobilities as high as 1.5x10(-3) cm(2)/Vs and with a current on/off ratio of 10(4).
