GdCl 3·6 H2O、H6 TPPS和组氨酸通过溶剂热反应合成了一种新的四（4-磺酸基苯基）钆卟啉-氨基酸杂化物，即{[Gd（His）（H2O）][Gd（H3 O）3]（H2 TPPS）2}n·3 nH 2 O（1）[His =组氨酸; H6 TPPS =四（4-磺酸基苯基）卟啉]。用单晶X射线衍射技术测定了配合物1的分子结构，表明卟啉大环为鞍形畸变，中心为非金属化。钆离子具有两种配位几何构型，一个扭曲的九配位单帽正方形反棱镜和一个扭曲的正方形反棱镜。配合物1是由钆离子将卟啉基团连接在一起而形成的三维结构。光致发光的研究表明，它显示在红色区域的发射。对配合物1的循环伏安/微分脉冲伏安、红外光谱和紫外-可见光谱进行了研究。它在红色区域显示发射
AbstractA solvothermal reaction of GdCl3·6H2O, H6TPPS, and histidine led to the formation of a novel gadolinium tetra(4-sulfonatophenyl)porphyrin–amino acid hybrid, namely, {[Gd(His)(H2O)][Gd(H3O)3](H2TPPS)2}n·3nH2O (1) [His = histidine; H6TPPS = tetra(4-sulfonatophenyl)porphyrin]. The molecular structure of complex1, which was determined by single-crystal X-ray diffraction technique, shows that the porphyrin macrocycle is saddle-distorted and its center is non-metalated. The gadolinium ions show two kinds of coordination geometry, i.e., a distorted nine-coordinated monocapped square antiprism and a contorted square antiprism. Complex1features a three-dimensional structure which is constructed from the gadolinium ions connecting the porphyrin moieties together. The photoluminescence study reveals that it displays an emission in the red region. The cyclic voltammetry/differential pulse voltammetry, FT-IR, and UV–Vis of complex1were also investigated in detail.Graphical AbstractA gadolinium tetra(4-sulfonatophenyl)porphyrin–amino acid hybrid was prepared. It displays an emission in the red region
