NTCDA–TTF first axial fusion: emergent panchromatic, NIR optical, multi-state redox and high optical contrast photooxidation

Abstract

The first synthetic entry into axially fused NTCDA/PMDA–TTF multipolar molecules demonstrates a high optical contrast photooxidation, panchromism, low HOMO–LUMO gap, generation of a stable radical cation, NIR absorption/emission beyond 2150/800 nm and theoretically calculated NLO activity.
