Amphiphilic synthetic receptors, reporter dyes and catalysts are embedded into the membrane of small unilamellar 100 nm vesicles where they self-assemble into patches. The size and composition of the patches depends on the compounds concentration, the nature of the lipids and the method of vesicle preparation. Due to the dynamic nature of the assembly and the close proximity of the molecules, binding of analytes to the embedded synthetic receptors triggers changes in the emission of co-embedded fluorescent dyes. The functionalized vesicles are therefore useful as luminescent soft chemosensors. Likewise, supramolecular photocatalysts are assembled using amphiphilic sensitizer dyes and redox active catalysts.References :B. Gruber, E. Kataev, J. Aschenbrenner, S. Stadlbauer, B.
