Radical cation salts and charge transfer complexes based on functionalized TTF derivatives

摘要

A series of new donors based on unsymmetricaltetrachalcogenofulvalenes bearing one or two NH_2 or OH groupshave been synthetized in order to help promoting extended H-bonding networks in potentially conductive compounds based onradical cation salts (RCS) and charge transfer complexes (CTC) systems.The synthesis route of these donors, designed to increaseselectivity and yield, is described. Preparation, stoichiometry,electrical properties, and in some cases X-ray structure analyses ofCl~-, Br~-, ReO_4~-, ClO_4~- as well as TCNQ salts of thesedonors are presented and discussed.
