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 (∼4.6 eV below the vacuum level), suitable for stable n-channel field-effect transistors (FETs) under ambient conditions. In fact, α-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 n-channel organic semiconductors.
并五噻吩并四氰基萘二甲烷（DTTNAPs）被合成并被评估为 n 通道有机半导体。DTTNAPs，无论其异构结构和取代基如何，都具有低的 LUMO 能级（低于真空能级约 4.6 eV），适合在环境条件下稳定的 n 通道场效应晶体管（FET）。实际上，α-DTTNAP 衍生物提供了溶液处理的 FET，表现出 10（-3）cm（2）V（-1）s（-1）的电子迁移率，表明 DTTNAPs 是 n 通道有机半导体的潜在分子框架。
