Three new silica gel-immobilized calix[4]arene polymers 9-11 have been prepared via modification of calix[4]arene mono amido derivatives 3-5 with 3-aminopropyl triethoxysilane (APTES) and activated silica gel, respectively. The polymers were characterized by Fourier transform infrared spectroscopy, elemental analysis and thermal gravimetric analysis. The solid-liquid extraction properties of ligands 3-5 along with their immobilized derivatives 9-11 towards dichromate (HCr(2)O(7)(-)/Cr(2)O(7)(2-)) anions were reported. It was found that these calix[4]arene-based polymers have high extraction abilities towards dichromate anions as compared to their monomeric precursors.
通过分别用3-氨丙基三乙氧基硅烷（APTES）和活化硅胶对杯[4]芳烃单酰胺衍生物3-5进行改性，制备了三种新型硅胶固定化杯[4]芳烃聚合物9-11。通过傅里叶变换红外光谱、元素分析和热重分析对聚合物进行了表征。报道了配体3-5及其固定化衍生物9-11对重铬酸根（HCr(2)O(7)(-)/Cr(2)O(7)(2-)）阴离子的固液萃取性能。结果发现，与它们的单体前体相比，这些基于杯[4]芳烃的聚合物对重铬酸根阴离子具有较高的萃取能力。
