A diarylethene annulated isomer as a highly-conductive molecular wire evaluated by the exchange interaction between two nitroxides

Abstract

Bis(imino nitroxide) bridged by a diarylethene annulated isomer was synthesized and the exchange interaction between the two radicals was determined by the simulation of the ESR spectrum. The exchange interaction was found to be as large as that of the closed-ring isomer, suggesting that the annulated isomer can be used as a highly-conductive molecular wire in molecular electronics.
