Abstract Solvothermal reaction of a multidentate ligand (tetrakis[4-(1-triazolyl)phenyl]-methane (ttpm)), with Cd(NO3)2 afforded a cationic Cd(II) coordination polymer {[Cd(ttpm)·DMSO]·2NO3}n. Single-crystal X-ray diffraction analyses showed that ttpm belonged to the tetragonal space group I41/a, and 1 was a 2-D (4,4) network. 1-D channels along the c direction exist in the 3D stacking map to accommodate the charge-balancing NO3− anions. N2 adsorption/desorption experiments showed the framework had a BET surface area of 11.36 m2·g−1. Compared with luminescence of ttpm, 1 showed red-shifted luminescence spectra with higher intensity from the more rigid arrangement of the π systems. Graphical Abstract

基于四(1,2,4-三唑-1-基)甲烷的阳离子Cd(II)金属-有机骨架

摘要 多齿配体（四[4-(1-三唑基)苯基]-甲烷 (ttpm)）与 Cd(NO3)2 的溶剂热反应得到了阳离子 Cd(II) 配位聚合物 {[Cd(ttpm)·DMSO] ·2NO3}n。单晶 X 射线衍射分析表明 ttpm 属于四方空间群 I41/a，1 是二维 (4,4) 网络。沿 c 方向的 1-D 通道存在于 3D 堆叠图中，以容纳电荷平衡的 NO3− 阴离子。N2 吸附/解吸实验表明该框架的 BET 表面积为 11.36 m2·g-1。与 ttpm 的发光相比，1 显示出具有更高强度的红移发光光谱，来自更刚性的 π 系统排列。图形概要
