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

Rh(III)-Co(III)-Rh（III）三核配合物的Rh（III）端羧酸基团Δ_<LLL>Δ_<LLL>-[Co-{Rh(L-cys-N，S)_3}_2]^<3->在水中用n -羟基琥珀酰亚胺和1-乙基-3-（3-二甲氨基丙基）盐酸碳二亚胺成功地与1,9-二氨基壬烷桥接。采用柱层析法对单阴离子肽桥式三核配合物进行分离纯化。通过^<31>C NMR、UV-vis和CD光谱对其结构进行了表征。用1,12-二氨基十二烷代替1,9-二氨基壬烷进行肽桥接反应。在类似的反应条件下制备了肽桥接聚合物配合物。证实了聚合物配合物中的硫代硫原子可以桥接并释放一些金属离子。

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.
