摘要:据报道,合成了一个4'-官能化的5,5'-二芳基-2,2'-联吡啶(bpy *;6A-6G)家族.这些配体与二聚体[(ppy)2 Ircl] 2(ppyh = 2-苯基吡啶)反应,并在随后的抗衡离子交换后提供了一系列新的发光阳离子杂原子铱(iii)配合物,[(ppy)2 Ir(Bpy *)] Pf 6(8A-8G).这些配合物通过电化学和光谱法表征.报道了其中两个复合物(8A和8G)的晶体结构.除8C和8F外的所有复合物在77 K和室温下,在2-Methf和acn中均表现出强烈且长寿命的发射.通过计算模型将这种发射的起源指定为配体到配体电荷转移的混合物[3 Llct; π(ppy)->π*(bpy *)]和金属到配体的电荷转移[3 Mlct; Dπ(ir)->π*(bpy *)]激发态,主要由前者组成.8A-8C的发光性质取决于固定在二亚胺配体上的芳基取代基在4'位置的官能化,而8D
