Influence of the Interlayer Interactions on Aggregates in Organic Molecular Films
Abstract:
Influence of the interlayer interactions on aggregates in Y-type Langmuir-Blodgett multilayers was investigated by using steady-state and time-resolved fluorescence techniques. As the interlayer interactions was screened by arachidic acid layers, intralayer interaction of hemicyanine molecules caused formation of H-aggregates and a blue shift of the fluorescence band in interleaving hemicyanine/arachidic acid multilayers. In pure Y-type hemicyanine multilayers, however, the molecules mainly formed J-aggregates leading to a significant red shift of fluorescence band and a larger scale of aggregates due to the stronger interlayer interactions.
