Enhanced π-frustration in carbo-benzenic chromophores

Chem Commun (Camb). 2013 Sep 28;49(75):8374-6. doi: 10.1039/c3cc43204a.

Abstract

The synthesis, structure, and absorption spectra of highly π-frustrated carbo-benzenes with indolic enamine substituents more or less directly conjugated to the C18 macro-aromatic core are described, and their peculiar reactivity is analyzed.
