Abstract

A new porphyrin-based coordination polymer, namely [Ni(TPPP)]_n·nDMF (JLNU-100), has been rationally synthesized under solvothermal condition (H₂TPPP = porphyrin-based ligand and DMF = N,N’-dimethylformamide). In JLNU-100, each Ni(II)-TPPP linker bridges two neighboring Ni(II) centers to afford a one-dimensional (1D) chain. These chains are further interlinked by C–H···π and π–π interactions to produce a 3D supramolecular architecture. The powder X-ray diffraction (PXRD) and UV-Vis diffuse-reflection spectrum (UV-Vis DRS) analyses reveal that JLNU-100 is stable and visible light responsible. Then, this material was used as an efficient photocatalyst for the degradation of methylene blue (MB) under visible light with a removal efficiency of 80.4%. 

摘要

在溶剂热条件下合理合成了一种新型卟啉基配位聚合物[Ni(TPPP)] _n ·nDMF ( JLNU-100 ) (H ₂ TPPP = 卟啉基配体，DMF = N , N'-二甲基甲酰胺) . 在JLNU - 100 中，每个 Ni(II)-TPPP 接头桥接两个相邻的 Ni(II) 中心以提供一维 (1D) 链。这些链通过 C–H…π 和 π–π 相互作用进一步相互连接，以产生 3D 超分子结构。粉末 X 射线衍射 (PXRD) 和紫外-可见漫反射光谱 (UV-Vis DRS) 分析表明JLNU-100是稳定和可见光负责。然后，该材料被用作有效的光催化剂，用于在可见光下降解亚甲蓝 (MB)，去除效率为 80.4%。
