摘要: 用荧光光谱滴定法研究了10种杯[4]芳烃硼酸与4种氨基酸的配位作用,根据扩展的Hilderbrand-Benesi公式,计算出配合物的稳定常数和配位反应的Gibbs自由能变化.杯[4]芳烃硼酸与L-丙氨酸的配位能力和配位选择性均较强,可以使用杯[4]芳烃硼酸通过荧光光谱法鉴别D-丙氨酸.

Abstract: Coordination of ten kinds of calix[4]arenes bearing boronic acid moieties with four kinds of amino acids was studied by using fluorescence spectrometry. The stability constants( Ks) of the complexes of calix[4]arenes bearing boronic acid moieties with amino acids and Gibbs free energy change(-Δ G °) of the coordination reactions were calculated according to the modified Hilderbrand Benesi equation. The results obtained indicated that the coordination abilities and selectivities of Lalanine with calix[4]arenes bearing boronic acid moieties were stronger than that of the other amino acids, and that the above calix[4]arene derivatives could be used for identification of D-alanine.

Key words: Calix[4]arene, Amino acids, Coordination, Fluorescence spectrometry
