Abstract:

Photoluminescence characteristics of four hemicyanine derivatives with similar molecular compositions but different donor acceptor groups in Langmuir Blodgett (LB) films have been studied by steady state and time resolved fluorescence spectroscopies. The study mainly include the aggregation behavior of hemicyanine derivatives in LB films, the influence of the donor acceptor on the excited level and excited lifetime of the hemicyenine derivatives.

Key words: LB multilayers, Aggregation, Time-resolved fluorescence
