绝对螺旋构筑的乳酸类非手性Cd(II)配位聚合物:合成、结构和荧光性质

, 2020
在溶剂热条件下,用半刚性对映配体(R)-4-(1-羧基乙氧基)苯甲酸((R)-4-(1-carboxyethoxy) benzoic acid, (R)-H2CBA)或(S)-4-(1-羧基乙氧基)苯甲酸((S)-4- (1-carboxyethoxy) benzoic acid, (R)-H2CBA)与辅助配体1,3,5-三(1H-咪唑-1-基)苯(1, 3, 5-tri (1H-imidazol-1-yl) benzene, TIB)一起与Cd(Ⅱ)反应得到一结构新颖的三维配位聚合物,也就是[Cd ...

一种具有新颖的二重自穿插(6,8)-双节点的三维超分子网络

, 2010
本文利用一个新的二羧酸配体5-羧基-1-羧甲基-2 氧吡啶(H 2 L), 合成了4 个异分同构的配合物, 通式为[M(HL) 2 (H 2 O)]·2H 2 O, M = Cu II (1), Zn II (2), Mn II (3), Cd II (4). 金属氯化物与配体H 2 L以1:2 的摩尔比在乙醇的水溶液中混合, 混合物在40~50 ℃下搅拌回流1 小时, 过滤后在室温下静置一周后, 得到适合X-射线单晶衍射分析的晶体, 产率为40%~50%.
