2′-bipyridine was conveniently synthesized from 2-bromopyridine through halogen-dance reaction, selective Kharash coupling and homo coupling of 2-bromopyridine derivative. Its corresponding ruthenium complex: cis - N , N -4,4′-di( p -methylphenyl)-2,2′-bipyridine- N , N -4,4′-dicarboxy-2,2′-bipyrine- N , N -dithiocyanato ruthenium(II) (dye-1) was also obtained and characterized by element analysis, MALDI-TOF

2,2'-联吡啶以2-
溴吡啶为原料,通过卤素-舞动反应、选择性Kharash偶联和2-
溴吡啶衍生物的均偶联反应合成了4,4'-二(对甲基苯基)-
2,2'-联吡啶。其对应的
钌络合物:顺式-N, N -4,4'-di(p-methylphenyl)-2,2'-bipyridine-N, N -4,4'-dicarboxy-2,2'-bipyrine-N,还获得了 N-二

钌 (II)(
染料 1),并通过元素分析、MALDI-TOF MS 和 H NMR 光谱对其进行了表征。与cis - N , N -2,2'-bipyridine-N , N -4,4'-dicarboxy-2,2'-bipyridine-N , N -dithiocyanato ruthenium(II)相比,
染料-1显示红移MLCT 吸收和增强的摩尔消光系数因其刚性 π 共轭。结果,
