Under ultrasonication, cadmium nitrate tetrahydrates, ethyl nicotinate (EN), and potassium thiocyanate as connecting ligand self-assembled to form the nanosized supramolecular coordination polymer (NSCP1) and the crystalline supramolecular coordination polymer (SCP1) [Cd(EN)₂(SCN)₂]. Single crystal SCP1 X-ray diffraction (XRD) revealed that Cd^II has an octahedral shape. The network structure of SCP1 is composed of chair conformation cyclic [Cd₂(SCN)₂]_n building blocks that form a one dimensional (1D) chain with bilaterally coordinated EN. The 1D-chain is joined to the other by extensive hydrogen bonds, which arrange the chains into a three-dimensional network. By stacking π–π, the strands are fluttering the three-dimensional (3D) network even more. Several structural characterization methods and spectral analyses were used to analyze SCP1 and NSCP1. The heterogeneous catalysts SCP1 and NSCP1 have been shown to display exceptionally strong catalytic activity against the breakdown of the designated contaminant, indigo carmine (IC) color in very short durations under ultraviolet (UV) or ultrasonic wave conditions. The photoluminescence probing approach was utilized to determine the reactive oxygen species and reaction process using the disodium salt of terephthalic acid.

基于镉、烟酸乙酯和硫氰酸酯配体的纳米超分子配位聚合物作为高效催化剂，去除废水中的有害元素


在超声处理下，硝酸镉四水合物、烟酸乙酯 （EN） 和硫氰酸钾作为连接配体自组装形成纳米超分子配位聚合物 （NSCP1） 和结晶超分子配位聚合物 （SCP1） [Cd（EN）₂（SCN）₂]。单晶 SCP1 X 射线衍射 （XRD） 显示 Cd^II 呈八面体形状。SCP1 的网络结构由椅子构象环状 [Cd₂（SCN）₂]_n 个构建块组成，这些构建块形成具有双侧配位 EN 的一维 （1D） 链。1D 链通过广泛的氢键连接到另一条链，这些氢键将链排列成一个三维网络。通过堆叠 π–π，这些链在三维 （3D） 网络中更加颤动。使用几种结构表征方法和光谱分析来分析 SCP1 和 NSCP1。非均相催化剂 SCP1 和 NSCP1 已被证明在紫外线 （UV） 或超声波条件下，在很短的时间内对指定污染物靛蓝胭脂红 （IC） 颜色的分解表现出非常强的催化活性。采用光致发光探测方法测定对苯二甲酸二钠盐的活性氧和反应过程。
