Using exciton trap (polymethine dye DiD) the efficiency of exciton energy transport in luminescent molecular nanoclusters (J-aggregates) of polymethine dye amphi-PIC has been investigated. It was shown that 50% of J-aggregates luminescence is quenched at the ratio amphi-PIC/DiD = 120, which points to effective energy transfer in the J-aggregates comparing with J-aggregates of another dyes. It was revealed that embedding of surfactant CPB leads to an increase in energy transfer efficiency due to suppression of localization processes in J-aggregates. In presence of CPB 50% of J-aggregates luminescence is quenched at the ratio amphi-PIC/DiD equal to 160.
