One host–two guests complexation between γ-cyclodextrin and sodium α-naphthylacetate as shown by excimer fluorescence

Abstract

The effect of increasing cyclodextrin (CD) concentration on the fluorescence spectra of sodium α-naphthylacetate is negligible for α-CD, large only in the normal fluorescence band for β-CD, and large for both the normal and the excimer fluorescence bands for γ-CD, showing the ability of γ-CD to form one host–two guests complexes.
