Energy transfer process in unsymmetrical crown-containing bisstyryl dye incorporated in the cavities of CB and 2-hydroxypropyl-β-CD
Supramolecular ternary assemblies based on unsymmetrical bisstyryl dye, CB and HP--CD have been prepared and studied by optical, NMR, ESI-MS and MD simulation methods. The free dye demonstrates the energy transfer (ET) between styryl fragments. The effectiveness of ET changes upon the capsulation by CB and HP--CD molecules. The explanation of the phenomenon was found from analysis of optical characteristics and MD modeling observation.
