Analysis of Binding Properties Between β-Cyclodextrin Bipyridine-ruthenium Derivative and Vitamins by Their Fluorescence Spectra
摘要
Abstract
This paper presents a research of the binding interaction of a new synthetized β-cyclodextrin bipyridine-ruthenium derivative[β-CD-Ru(bpy) 3] with a series of vitamins using fluorescent spectrometry.The performance of fluorescence emission ofβ-CD-Ru(bpy) 3 was excellent due to the existence of the center of bipyridine-ruthenium.Based on the effect of molecular recognition betweenβ-cyclodextrin and guest molecule,the fluorescence quenching occured because of the energy transfer between theβ-CD-Ru (bpy) 3 and the vitamin when a kind of vitamin was added.According to the quantitative value of fluorescence quenching,the binding constants of the new derivative with respect to various vitamins were determined by Benesi-Hildebrand Equation.The results show that the binding capacities of the vitamins withβ-CD-Ru (bpy) 3 were in a descending sequence of VB12＞VK3 ＞VC＞VA.关键词
