Abstract:
Two novel emissive amphiphilic molecules with intramolecular charge transfer character (HAPMP and HAPEOP) were synthesized, and their self-assembled particles were obtained in an aqueous solution. SAXS analysis and TEM observation showed that these self-assemblies exhibited vesicle-like structures. Analysis using the indirect Fourier transformation (IFT) method for their bilayer structures indicated that HAPMP was arranged in a vertical orientation relative to the bilayer plane, whereas HAPEOP adopted a tilted orientation. The maximum emission wavelengths in their vesicle states were red-shifted compared with those in the monomeric state. Time-resolved emission spectroscopy revealed prolonged emission lifetimes, suggesting that they formed an excimer in the bilayers.
