Abstract

A new series of diisocyanide-bridged homodinuclear Re(I) complexes [(phen)(L_x)(CO)₂Re(CNRNC)Re(CO)₂(L_x)(phen)]²⁺ and their mononuclear analogues [Re(PPh₃)(CNRNC)(CO)₂(phen)]⁺ [L_x = CO and PPh₃; CNRNC = 1,4-phenylenediisocyanide (CNC₆H₄NC) and 4,4′-biphenyldiisocyanide (CNC₆H₄C₆H₄NC)] have been synthesized. The X-ray crystal structures of two of the dinuclear complexes were determined. The photophysics and electrochemistry of these complexes have been investigated. The dicarbonyl phosphino Re(I) phenanthroline complexes display intense MLCT [dπ(Re)→π^∗(phen)] phosphorescence in CH₂Cl₂ solution with luminescence quantum yield (φ_em) in the range of 0.127-0.171. In contrast, the tricarbonyl dinuclear Re(I) complexes exhibit LC [π→π^∗(phen)] phosphorescence with φ_em from 0.0498 to 0.0625.
