2′-bipyridines functionalized with a perylene or a perylenediimide moiety were synthesized and the corresponding heteroleptic ruthenium(II) complexes ([Ru(bpy)2(L)](PF6)2; bpy = 2,2′-bipyridyl, L = perylene-substituted bpy ligand) were prepared. The UV–vis spectra of the ruthenium(II) complexes showed red-shifted and intense absorption bands derived from the conjugated structure of the new ligands.
合成了五个用new或a二酰亚胺部分官能化的新的2,2'-联吡啶,并形成了相应的杂配钌(II)配合物([Ru(bpy)2(L)](PF 6)2; bpy = 2,2' (-联吡啶基,L = per取代的bpy配体)。钌(II)配合物的紫外-可见光谱显示出红移和强烈的吸收带,这些吸收带源自新配体的共轭结构。
