Tetraceno[2,1,12,11-opqra]tetracene-extended tetrathiafulvalene – redox-controlled generation of a large PAH core

Abstract

Two tetraceno[2,1,12,11-opqra]tetracene-extended tetrathia-fulvalenes were prepared and found to undergo reversible conversion into their planar polycyclic aromatic hydrocarbons (PAHs) upon electrochemical oxidation - at potentials probing the best valence bond representations.
