Mixed Valence in Conjugated Anion Radicals. Solution and Solid State Studies

Abstract

Electron localization in anion radicals of aromatic compounds built with two electrophores was studied using Vis, NIR, IR, and ESR spectroscopy and electrochemistry. N,N',-Bis(2,5-di-tert-butylphenyl)-2,3,6,7-anthracene- dicarboximide anion radical has the odd electron mainly localized on the anthracene bridge. This contrasts with its diquinone analog, 1, 4,8,11- pentacenetetrone, which has the odd electron localized on one quinone at a time. The anion radical of the tetrakis-(N-cyanoimine) derivative of 5, 7, 12, 14- pentacenetetrone (3-) is delocalized.
