The preparations, photophysical and electrochemical properties of a series of fac-[Re(CO)3(diimine)Br] complexes are presented. The bipyridine (bpy) based diimine ligands feature symmetrical and asymmetrical 3,3’-diamino-2,2’-bipyridine substitution patterns. Photophysical and electrochemical properties of these complexes are tunable, depending on their organic diimine framework. Introduction of a
介绍了一系列fac -[Re(CO) 3 (diimine)Br] 配合物的制备方法、光物理和电化学性质。基于联吡啶 (bpy) 的二亚胺配体具有对称和不对称的 3,3'-二氨基-2,2'-联吡啶取代模式。这些配合物的光物理和电化学性质是可调的,具体取决于它们的有机二亚胺骨架。通过3,3'-取代模式引入远端尿素桥导致磷光寿命延长,而吸光度和磷光发射波长没有显着变化。通过这种衍生化,可逆电化学联吡啶还原基本保持不变。
