Novel reversible ionic-to-covalent transition in a highly conducting TTF derivative

J Am Chem Soc. 2003 Dec 31;125(52):16206-7. doi: 10.1021/ja037621n.

Abstract

TTF produces two completely different phenomena with the different isomers of chloranil; with the para isomer it produces an insulating, alternating stack, ambient temperature neutral solid. While with the ortho isomer, it produces a more interesting system consisting of interconvertible conducting ionic and covalent components.
