The tristhiourea tripodal metal complexes are a group of coordination compounds having a transition metal linked by coordinate covalent bods to a chelating agent. The chelating agent has a tris-(6-amino-2-pyridylmethyl)amine (TAPA) backbone and three thiourea ligands bonded to the three legs of the TAPA backbone, respectively. The transition metal bonds to the amino groups of the TAPA backbone, and the thiourea ligands hydrogen bond to the anion guest remote from the transition metal. The chelating agent has a symmetrical C3v tripodal cavity that is selective for tetrahedral anions. The transition metal is selected from the group consisting of cadmium, manganese, cobalt, nickel, copper, and zinc. The tristhiourea tripodal metal complexes may be used in colorimetric sensors, selectively permeable membranes, filtration media for separating tetrahedral anions (such as phosphate and perchlorate) from mixtures, and similar applications.
三硫脲三脚架金属配合物是一类配位化合物,其中过渡金属通过配位共价键与螯合剂相连。螯合剂具有三-(6-氨基-2-吡啶甲基)胺(TAPA)骨架,三个硫脲配体分别与TAPA骨架的三条腿结合。过渡金属与TAPA骨架的氨基结合,硫脲配体与远离过渡金属的阴离子客体形成氢键。螯合剂具有对四面体阴离子具有选择性的对称C3v三脚架空腔。过渡金属选自镉、锰、钴、镍、铜和锌。三硫脲三脚架金属配合物可用于比色传感器、选择性渗透膜、用于从混合物中分离四面体阴离子(如磷酸盐和高氯酸盐)的过滤介质等应用。
