Dinuclear gold(I) complexes [mu-(4,4'-CN-R-NC)Au(C6F4OC4H9)}2] [R = 1,4-phenylene, n = 8; R = 4,4'-biphenylene, 2,2'-dichloro-4,4'-biphenylene, 2,2'-dimethyl-4,4'-biphenylene, n = 4,6,8,10] have been prepared and their liquid crystal behavior and optical properties studied. Although the free ligands are not mesomorphic, all the gold(I) derivatives described, except the phenylisonitrilegold(I) derivative
双核金(I)配合物[mu-(4,4'-CN-R-NC)Au(C6F4OC4H9)} 2] [R = 1,4-亚苯基,n = 8;制备了R = 4,4'-联苯,2,2'-二氯-4,4'-联苯,2,2'-二甲基-4,4'-联苯,n = 4,6,8,10]并研究了它们的液晶行为和光学性质。尽管游离配体不是介晶的,但所描述的所有金(I)衍生物,除了苯基异三烯三酚(I)衍生物[mu-(1,4-CN-C6H4-NC)Au(C6F4OC8H17)} 2]均显示液晶行为,导致向列中间相。转变温度以4-4'-联亚苯基> 2,2'-二氯-4-4'-联亚苯基> 2,2'二甲基-4-4'-联亚苯基的顺序降低。所有化合物在固态和溶液中均显示出光致发光。[μ-(4,4' -CN-R-NC)Au(C6F4OCnH2n + 1)} 2](R = 4-4'-联亚苯基和2,2'-二氯-4-4'-联亚苯基)已确定,确
