研究ｎ－β（氨乙基）－γ（氨丙基）三乙氧基硅烷［ＮＨ２（ＣＨ２）２ＮＨ（ＣＨ２）３Ｓｉ（ＯＥｔ）３］与二甲基二乙氧基硅烷［（ＣＨ３）２Ｓｉ（ＯＥｔ）２］共水解，制备含－（ＣＨ２）３ＮＨ（ＣＨ２）２ＮＨ２功能基的聚硅氧烷配位体。用ＩＲ、１ＨＮＭＲ和元素分析法对共聚产物的结构进行了分析，同时用紫外－可见光谱法和ＳＥＭ考察了共聚产物与Ｃｕ２＋等金属离子的络合作用。结果发现，两种单体进行了共水解反应，而且随着ＮＨ２（ＣＨ２）２ＮＨ（ＣＨ２）３Ｓｉ（ＯＥｔ）３比例增加，水解程度提高。共聚产物可以与Ｃｕ２＋离子形成稳定的络合物，但不能与Ｚｎ２＋离子或Ａｌ３＋离子形成稳定的络合物或螯合物。
The effects of n-β (aminoethyl) -γ (aminopropyl) triethoxysilane [NH2 (CH2) 2NH (CH2) 3Si (OEt) 3] and dimethyldiethoxysilane [(CH3) 2Si (OEt) 2] to prepare a polysiloxane ligand containing - (CH2) 3NH (CH2) 2NH2 functional groups. The structure of the copolymer was analyzed by IR, 1HNMR and elemental analysis. The complexation of the copolymer with Cu2 + and other metal ions was investigated by UV-Vis spectroscopy and SEM. As a result, it was found that the two monomers were subjected to the co-hydrolysis reaction, and the degree of hydrolysis increased as the proportion of NH2 (CH2) 2NH (CH2) 3Si (OEt) 3 increased. Copolymers can form stable complexes with Cu2 + ions but can not form stable complexes or chelates with Zn2 + ions or Al3 + ions.
