为研究环糊精形成超分子配合物的性能 ,合成了环己胺修饰 β-环糊精与嗪的固态超分子配合物 ,并进行了元素分析、红外光谱、核磁共振、热分析等结构参数的表征 .采用荧光光谱研究了该固态超分子配合物的发光性质 ,并与嗪进行了比较 ,发现超分子配合物较嗪荧光最大发射波长蓝移了 1 5 5 nm,荧光发射强度增强了 4.9倍 ,半峰宽变窄了 5 1 nm
In order to study the performance of cyclodextrins in the formation of supramolecular complexes, a solid supramolecular complex of cyclohexylamine modified β-cyclodextrin and pyrazine was synthesized and characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance and thermal analysis The luminescent properties of the supramolecular complexes were investigated by fluorescence spectroscopy and compared with that of phenanthroline. The results showed that the maximum wavelength of fluorescence of supramolecular complexes shifted blue by 155.5 nm, the fluorescence emission intensity 4.9 times increase, half-width narrowed by 5 1 nm
