Abstract Three coordination polymers, {[CdI(DBBA)]∙0.5H2O}n (1, DBBA = 3,5-di(1Hbenzo[d]imidazol-1-yl)benzoate), [Cd(DBBA)(CH3COO)]n (2) and [Cd(DBBA)2]n (3), were obtained through reactions between Cd(II) salts and 3,5-di(1H-benzo[d]imidazol-1-yl)benzoic acid under different pH conditions. Compounds 1 and 2 are 3-D frameworks with rtl topology based on different binuclear Cd(II) secondary building units. Compound 3 was formed at lower pH and showed a 1-D chain assembled with M2L2 ring units. Moreover, phase purities, thermal behaviors, and photoluminescent properties have also been investigated.

基于 3,5-di(1H-benzo[d]imidazol-1-yl)benzoate 的三种 Cd(II) 配位聚合物的阴离子和 pH 调节组装

摘要 三配位聚合物, {[CdI(DBBA)]∙0.5H2O}n (1, DBBA = 3,5-di(1Hbenzo[d]imidazol-1-yl)benzoate), [Cd(DBBA)(CH3COO)] n (2) 和 [Cd(DBBA)2]n (3)，是通过 Cd(II) 盐与 3,5-二(1H-苯并[d]咪唑-1-基)苯甲酸在不同条件下反应得到的。 pH条件。化合物 1 和 2 是具有基于不同双核 Cd(II) 二级构建单元的 rtl 拓扑结构的 3-D 框架。化合物 3 在较低的 pH 值下形成，并显示出由 M2L2 环单元组装而成的一维链。此外，还研究了相纯度、热行为和光致发光特性。
