We used a squarylium dye SQ as a specific exciton trap for J aggregates of the amphiphilic cyanine dye amphi-PIC. The exciton transport parameters in amphi-PIC J aggregates were estimated using a modified Stern–Volmer equation. We found that SQ quenches 50% of the luminescence of amphi-PIC J aggregates for a ratio of 1 SQ molecule per 80 amphi-PIC molecules.
