技术领域
本发明属于有机配合物合成技术领域,具体涉及一种金属络合物及其制备方法与应用。
背景技术
公开该背景技术部分的信息旨在增加对本发明总体背景的理解,而不必然被视为承认或以任何形式暗示该信息构成已经成为本领域一般技术人员所公知的现有技术。
2012杜凯等,分别以1,3,5-苯三甲酸(H3BTC)、苯六甲酸(H6MTA)和1,2,3,4,5,6-环己六甲酸(H6CCA)为配体合成了Eu(III)的二元发光配合物Eu(BTC)·2H2O,Eu2(MTA)·4H2O和Eu2(CCA)·4H2O。通过元素分析、红外光谱和等离子体原子发射光谱对其化学组成进行了结构表征。(张尽力,赵利平,罗炫等.多羧酸根铕二元配合物的合成及光谱分析[J].化学学报,2012,70(05):679-682.)。
甲壳胺(Chitosan,简写为CT S)是甲壳素脱乙酰基的产物,是一种线性半刚性高分子,由于CT S分子中有—NH2、—OH和—NHCOCH3,故它对过渡金属具有很强的螯合能力。俞贤达等在均相反应条件下合成了Cu(II)、Ni(II)和Zn(II)与CT S的配合物,通过元素分析首次确定了配合物的组成。(王爱勤,张平余,俞贤达.甲壳胺与铜(II)、镍(II)、锌(II)配合物的合成及性质[J].化学通报,1999(08):32-34.DOI:10.14159/j.cnki.0441-3776.1999.08.006.)。
