| Outline of Final Research Achievements |
In this study, higher-order structures composed of cationic lipids and anionic dyes were constructed on solid substrates based on static self-assembly far from thermodynamic equilibrium. Photon energy migration properties of the obtained superstructures were characterized by using confocal laser scanning microscopy. Coral reef-like superstructures were formed spontaneously by dropping an aqueous solution of anionic cyanine dye onto the spin-cast film of a dialkylammonium (2C16) bromide. The cyanine dyes formed J-aggregates in the superstructures, and efficient fluorescence resonance energy transfer from the cyanine J-aggregates to acceptor dyes occurred, which can be utilized for fluorescence sensitization of biological molecules at the interface.
