摘要：

Three bis(bidentate) ligands cis-di(4,5-diazafluoren-9-ylimino)dibenzo-14-crown-4 (BL1), trans-di(4,5-diazafluoren-9-ylimino)dibenzo-14-crown-4 (BL2), and 1,4,8,11-tetraoxacyclotetradecyl[2,3:9,10]bis-dipyrido[3,2-a:2'3'-c]phenazine (BL3), and corresponding bimetallic Ru(II) complexes [(bpy)(2)RuBL1-3Ru(bpy)(2)](PF6)(4) (Ru-BL1-3) have been synthesized. Cyclic voltammetry of these complexes are consistent with one Ru(II)-centered reversible oxidation and three ligand-centered reductions. These complexes show metal-to-ligand charge transfer absorption at 445-454 nm and emission at 575592 nm. (c) 2008 Elsevier B.V. All rights reserved.
