摘    要:利用稳态、时间分辨荧光光谱,结合非线性最小二乘法拟合系统研究了手性探针分子丹酰-L-丝氨酸(DLS)与β-环糊精(β-CD)、2-位硒桥联β-CD(1)和2-位碲桥联β-CD(2)的复合及复合机理.对比研究了DLS与三种不同环糊精复合强度及复合方式的差别.结果表明,引入硒桥键不能使化合物1与丹酰基丝氨酸分子很好地复合;而引入碲桥键使化合物2对DLS分子的结合能力相对于β-CD有明显增强.

关 键 词:丹酰基丝氨酸  硒桥联双环糊精  碲桥联双环糊精  非线性最小二乘法拟合  时间分辨荧光光谱

Abstract:Time-resolved fluorescence spectra were applied to study the binding of dansyl-L-serine(DLS) with β-cyclodextrin(β-CD), 2-selenium bridged β-cyclodextrin(1) and 2-tellurium bridged β-cyclodextrin(2). The differentiations of DLS in binding with three kinds of cyclodextrins were performed. The results suggest that compound 1 cannot bind with DLS efficiently. However, compound 2 can enhance the binding ability with DLS greatly in comparison with that of β-CD.
Keywords:Dansyl-L-serine  2-Selenium bridged β-cyclodextrin  2-Tellurium bridged β-cyclodextrin  Non-linear least-square curve fitting  Time-resolved fluorescence spectroscopy
