Interaction between molecular aggregates placed into thin layered films

Interaction of J-aggregates of two carbocyanine dyes, TDBC and TCC, with similar structures has been studied in aqueous solutions and thin polymer films. It has been revealed that despite the structure similarity these J-aggregates didn't interact explicitly when mixed both in aqueous solutions...

Description
Summary:Interaction of J-aggregates of two carbocyanine dyes, TDBC and TCC, with similar structures has been studied in aqueous solutions and thin polymer films. It has been revealed that despite the structure similarity these J-aggregates didn't interact explicitly when mixed both in aqueous solutions and polycation thin films. However, by placing the J-aggregates in different layers separated by polycation film spacer, efficient energy transfer can be achieved with TDBC J-aggregates as an energy donor and TCC J-aggregates as energy acceptor.
