【摘要】 设计合成了下缘连有氨基苯氧基结构的杯[4]芳烃衍生物:5,11,17,23-四叔丁基-25-[2-(2-氨基苯氧基)乙氧基]-27-(2-羟基乙氧基)-26,28-二羟基杯[4]芳烃(化合物C),增加了与阳离子的结合位点,有利于通过配位作用对金属离子进行识别。化合物C的结构通过红外光谱、1H NMR、13C NMR和质谱进行了表征。通过紫外可见光谱和荧光发射光谱对化合物C与24种金属阳离子的络合作用进行了研究,结果发现,其对La3+有特殊的识别作用,化合物C与La3+的络合比为1∶1。更多还原

【Abstract】 A novel aminophenol calix[4]arene derivative,5,11,17,23-tetra-t-butyl-25-[2-( 2-aminophenoxy)-ethyoxyl]-27-( 2-hydroxyethoxyl)-26,28-bihydroxycalix[4]arene,was designed and synthesized. The amino-phenoxy structure was appended at the lower rim of calix[4]arene,so the binding sites with cation and recognition capability for metal ions were increased by the effect of coordination. The structure of as-synthesized compound was characterized using IR,1H NMR,13 C NMR and MS. The complexation between it and 24 kinds of metal cations was studied by fluorescence emission and UV-Vis spectra. The results showed that it exhibits the preferential recognition reaction with La3 +. The stoichiometry of host guest complexation has been determined to be 1∶ 1.更多还原
