Star-Shaped Tetrathiafulvalene-Fused Coronene with Large π-Extended Conjugation

A tristar shaped, planar TTF-fused coronene I was synthesized, its electronic properties have been studied experimentally by the combination of electrochemistry and UV-vis-NIR spectroscopy. Thereby, a nanosized graphite fragment is largely extended in its size, supplemented with a multielectron donor functionality, and shaped to a strongly chromophoric species absorbing intensely in the visible part of the optical spectrum.
