Four rhenium(I) complexes ReL1–ReL4 based on dipyrido[3,2-a:2′,3′-c]phenazine (L1) and derivatives L2-L4 ligands (L2: 10,13-dibromodipyrido[3,2-a:2′,3′-c]phenazine, L3: 10-bromo-13-carbazolyl-dipyrido[3,2-a:2′,3′-c]phenazine, L4: 10,13-dicarbazolyldipyrido[3,2-a:2′,3′-c]phenazine) were synthesized and characterized. The Re(I) complexes ReL1–ReL4 show photoluminescent emissions at 556, 582, 637 and
基于双吡啶并[3,2-a:2',3'-c]吩嗪(L1)和衍生物L2-L4配体(L2:10,13-二溴二吡啶[3,2- a:2',3'-c]吩嗪,L3:10-溴-13-咔唑基-二吡啶并[3,2-a:2',3'-c]吩嗪,L4:10,13-二咔唑基二吡啶并[3, 2-a:2',3'-c]吩嗪)被合成和表征。Re(I) 复合物 ReL1-ReL4 分别在 556、582、637 和 662 nm 处显示光致发光发射,分配给 CH2Cl2 溶液中的 d (Re)→* (二亚胺) MLCT 磷光。与 ReL1 相比,含有咔唑的复合物 ReL3 和 ReL4 表现出更高的发光。这些观察结果表明,用咔唑部分修饰二亚胺铼 (I) 羰基配合物将导致有效的磷光特性。
