摘要
杯芳烃(Calixarenes)[1]是由苯酚单体通过亚甲基单元连接起来的一类性质稳定的环状低聚物.由于它的独特结构特点以及由此表现出来的特有性能,使之已成为继冠醚和环糊精之后的第三代超分子[2].近年来,杯芳烃在色谱中的应用已经引起人们的关注,有关...
A new method was used to prepare a calix [4] arene-bonded silica stationary Phase. The chemically modified calix[4] arene 1 was attached to silica gel via the silane coupling reagent y(ethylenediamino ) - propyl - triethoxyl - silane. The resulting bonded phase was characterized by 29 Si and 13C cross polarization/magic angle spinning(CP/MAS) nuclear magnetic resonance(NMR) techniques.
