摘要

Three complexes [Cu₂(pz)(pda)₂(CH₃CN)₂](BF₄)₂ (1), [Cu₂(tpphz)(pda)₂](BF₄)₂(CH₃CN)₄ (2) and [Cu₂(bfimbz)(pda)₂](BF₄)₂ (3) (pba = N,N鈥?bis((diphenylphosphino)methyl)benzenamine, pz = pyrazine, tpphz = tetrapyrido[3,2-a:2鈥?3鈥?c:3鈥?2鈥?h:2鈥?3鈥?j]phenazine, bfimbz = 1,4-bis([1,10]-phenanthroline[5,6-d]imidazol-2-yl)-benzene) have been synthesized. They are centrosymmetric dinuclear complexes constructed respectively by bridging imine ligands of pz, tpphz and bfimbz linking two [Cu(pda)] moieties. Ligand pda performs as a terminal bidentate ligand. The solid state luminescence of 1, 2 and 3 are 542, 632 and 584 nm, respectively, while their lifetimes are 86.6, 78.5 and 37.8 渭s respectively. The rigid 蟺-conjugated system of the imine ligand could play an active role in intramolecular photoinduced energy or electron transfer between two Cu⁺ moieties.
