Synthetic Study of Polymer Complex Thin Membrane which penetrates small organic molecules and Separates, Concentrates, Identifies, and Recovers Heavy Metal ions

用N-羟基丁二酰亚胺和1-乙基-3-（3-二甲氨基丙基）碳二亚胺盐酸盐在水中成功地将Rh（Ⅲ）-Co（Ⅲ）-Rh（Ⅲ）三核配合物Δ_<LLL>Δ_<LLL>-[Co-{Rh（L-cys-N，S）_3}_2]^的Rh（Ⅲ）端<3->羧基与1，9-二氨基壬烷桥连。通过柱层析分离纯化单阴离子肽桥三核复合物，然后分离。通过13 <31>C NMR、UV-vis和CD光谱确定了其结构。肽桥连反应也通过使用1，12-亚氨基十二烷代替1，9-二氨基壬烷进行。在类似的反应条件下制备肽桥接的聚合物复合物。结果表明，聚合物配合物中的巯基硫原子可以桥接并释放出部分金属离子。

Carboxylate groups in the Rh(III) terminals of Rh(III)-Co(III)-Rh(III) trinuclear complex, Δ_<LLL>Δ_<LLL>-[Co-{Rh(L-cys-N,S)_3}_2]^<3-> were successfully bridged with 1,9-diaminononane using N-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride in water. The monoanionic peptide-bridged trinuclear complex was separated and purified by column chromatography, and then isolated. The structure was determined by ^<31>C NMR, UV-vis, and CD spectra. The peptide-bridged reaction also proceeded by using 1,12-diminododecane instead of 1,9-diaminononane. The peptide-bridged polymer complex was prepared under a similar reaction conditions. It was confirmed that the thiolato sulfur atoms in the polymer complex can bridge and release some metal ions.
