Exciton transport in amphi-PIC J-aggregates formed in polymer films
Abstract
J-aggregates of amphi-PIC dye have been successfully formed in polymer films by layer-by-layer assembly method. Another dye embedded into J-aggregate layer has revealed itself as efficient exciton trap, which trapped about 80% of excitons. Analyzing J-aggregate luminescence quenching using modified Stern-Volmer equation it has been found that 1 DiD molecule quenches 50% luminescence of 60 amphi-PIC molecules forming the J-aggregate. That is half as much compared to the solution case. The reason for such difference discussed.
