Star-shaped tetrathiafulvalene-fused coronene with large pi-extended conjugation

J Org Chem. 2009 Aug 7;74(15):5727-9. doi: 10.1021/jo901054b.

Abstract

A tristar shaped, planar TTF-fused coronene 1 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.
