The energetic transfer behavior of the molecular excited states in a fully synthesized bilayer membrane was investigated. The donor was a biphenyl chromophore on the vesicle amphiphile. The receptor was a fluorescent yellow anion that bound to the vesicle surface through electrostatic interactions. Fluorescence yellow quenching biphenyl fluorescence intensity in line with the law of Sern-Volmer quenching. The effect of vesicles on the energy transfer process, the efficiency and mechanism of the transfer were discussed. By studying the electrostatic transfer of energy between the fluorescent yellow donor and the tetraphenylporphyrin acceptor bound to the vesicle surface, the light output is improved and the light wave coverage is extended. Fully synthetic bilayer membranes are effective mediators of energy transfer and good membrane mimics.
