A new rhenium(i) tricarbonylpolypyridine donor–acceptor complex featuring a long-lived charge-separated excited state

Abstract

The new mononuclear complex [(DEAS-bpy)Re(CO) ₃ (BPP)] ⁺ is prepared {DEAS-bpy = 4,4′-bis[p-(diethylamino)-α-styryl]-2,2′-bipyr idine, BPP = 1,10-bis(4-pyridyl)-3,8-dimethyl-1,3,5,7,9-decapentaene} in which electrochemical and photophysical properties clearly indicate the presence of a long-lived charge-separated excited state at room temperature upon light excitation.
