title: Dithiophene-Fused Tetracyanonaphthoquinodimethanes (DT-TNAPs): synthesis and characterization of π-extended quinoidal compounds for n-channel organic semiconductor.
abstract: 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.
