Unexpected Formation of <i>ortho</i>-Benzoquinone-fused Tetraselenafulvalene (TSF): Synthesis, Structures, and Properties of a Novel TSF-based Donor–Acceptor Dyad
Access this Article
Electrochemical oxidation of a catechol-fused tetraselenafulvalene (TSF) derivative unexpectedly gave its <i>ortho</i>-benzoquinone analogue, in contrast to the tetrathiafulvalene (TTF) system that afforded a hydrogen-bonded organic conductor. The obtained donor–acceptor dyad showed amphoteric redox character, a small HOMO–LUMO gap, effective intermolecular interactions, and NIR absorption.
