Charge instability of symmetry broken dipolar states in quadrupolar and octupolar triphenylamine derivatives

Chem Commun (Camb). 2014 Jul 4;50(52):6902-5. doi: 10.1039/c3cc47514j.

Abstract

The quadrupolar and octupolar cyano triphenylamines shows symmetry broken dipolar charge transfer state, however, its stability can be controlled by the rotation of N-C bond of amino and phenylene moiety.
