Аннотация:Supramolecular ternary assemblies based on unsymmetrical bisstyryl dye, CB[7] and HP-b-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[7] and HP-b-CD molecules. The explanation of the phenomenon was found from analysis of optical characteristics and MD modeling observation
