摘要

Dithiophene-fused tetracyanonaphthoquinodimethanes (DTTNAPs) were synthesized and evaluated as n-channel organic semiconductors. DTTNAPs, regardless of isomeric structures and substituents, have low-lying LUMO energy levels (similar to 4.6 eV below the vacuum level), suitable for stable n-channel field-effect transistors (FETs) under ambient conditions. In fact, alpha-DTTNAP derivatives afforded solution-processed FETs showing an electron mobility of 10(-3) cm(-2) V-1 s(-1), indicating that DTTNAPs are a potential molecular framework for channel organic semiconductors.
