以5-(4-羟基苯基)-10,15,20-三苯基卟啉作为卟啉单体,通过反丁烯二酰基桥联合成出一种卟啉二联体(DP),并将其与多种金属离子配位得到了一系列金属卟啉配合物。通过金属配合物与氧化石墨烯(GO)杂化复合,制备出新型的金属卟啉二联体-GO复合材料。通过扫描电子显微镜(SEM)、紫外-可见吸收光谱(UV-Vis)、红外光谱(FT-IR)等手段进行表征。结果表明:该二联体与GO的结合方式为π-π非共价键堆积。为了研究该复合材料的光降解性能,选用亚甲基蓝(MB)为模型有机污染物,研究不同光源条件下复合材料的催化降解效率。
A kind of porphyrin dimer(DP) bridged by trans butene diacyl which was synthesized from 5-(4-hydroxyphenyl)-10,15,20-triphenyl porphyrin.A series of metalloporphyrin complexes were obtained by coordination with a variety of metal ions.A novel metalloporphyrin dimer/graphene oxide composite(M-DP/GO) was prepared by hybrid recombination of porphyrins metal complexes and GO.Using some studies such as SEM techniques,UV-Vis,and IR which showed that GO can effectively combine with porphyrin dimer complexes by the π-π non covalent interaction.In order to study the photodegradation performance of the composite,methylene blue (MB) was selected as the model organic pollutant to study the catalytic degradation efficiency of the composite under different light sources.
