Abstract

Abstract : A supramolecular complex of an unsymmetrical crown-containing bisstyryl dye with CB[7] and 2-hydroxypropyl-β-CD can operate as an energy transfer system. Abstract : Supramolecular ternary assemblies based on an unsymmetrical bisstyryl dye, CB[7] and HP-β-CD have been prepared and studied by optical, NMR, ESI-MS and MD simulation methods. The free dye demonstrates energy transfer (ET) between styryl fragments. The effectiveness of ET changes upon encapsulation by CB[7] and HP-β-CD molecules. The explanation of the phenomenon was found from analysis of the optical characteristics and MD modeling observations.
