A one‐dimensional looped chain coordination polymer (CP1) is synthesized by the reaction of CoII with N1,N3‐di(pyridine‐4‐yl)isophthalamide. Transmetalation reaction of CP1 with CuII showed single‐crystal‐to‐single‐crystal (SC‐SC) transformation to form CP2, which is also a 1D looped chain. Both CP1 and CP2 showed the presence of DMF as guest molecules near the loops of the 1D chains. CP1 and CP2 were found to have bandgap of 2.41 eV and 1.30 eV, respectively, which were calculated by Tauc plot. The difference observed in the optical bandgap of CP1 and CP2 is reflected in photocatalytic dye degradation studies. It was observed that CP2 showed much greater efficiency in degrading the dyes (Methylene blue, Methyl orange and Rhodamine B) as compared to that of CP1. The polar nature of the loops of the chains in CP1 and CP2 due to the presence of DMF was exploited to study the adsorption and desorption of I2. Adsorption of I2 in CP1 and CP2 was found to follow first order kinetics with a rate constant of 8.32 × 10–5 s–1 for CP1 and 9.71 × 10–5 s–1 for CP2. Guest inclusion reaction was performed to incorporate benzotriazole in the CP1. Impedance measurements showed a higher conductivity in the benzotriazole incorporated CP1.

双吡啶基二酰胺衍生的合成后修饰的配位聚合物的光催化活性增加
Co II与N 1，N 3-二（吡啶-4-基）间苯二甲酰胺反应合成了一维环状链配位聚合物（CP1）。CP1与Cu II的金属转移反应表明单晶至单晶（SC-SC）转化形成CP2，这也是一维环状链。无论CP1和CP2表明DMF的存在，作为一维链的环附近的客体分子。CP1和CP2通过Tauc曲线计算得出的带隙分别为2.41 eV和1.30 eV。在CP1和CP2的光学带隙中观察到的差异反映在光催化染料降解研究中。观察到，与CP1相比，CP2在降解染料（亚甲基蓝，甲基橙和若丹明B）方面显示出更高的效率。由于DMF的存在，CP1和CP2中链环的极性性质被用来研究I 2的吸附和解吸。我吸附2在CP1和CP2被发现遵循一级动力学具有8.32×10的速率常数-5小号-1为CP1和9.71×10 -5小号-1为CP2。进行客体包含反应以将苯并三唑掺入CP1中。阻抗测量结果表明，结合了苯并三唑的CP1具有更高的电导率。
