Self-Assembly Into Spheres of a Hybrid Diphenylalanine-Porphyrin: Increased Fluorescence Lifetime and Conserved Electronic Properties

A series of protected phenylalanine and diphenylalanine derivatives have been coupled through a peptide bond to a monoaminoporphyrin to form new materials. A comparative study in solution and in the solid state has been performed and confirmed new and interesting properties for the self-assembled hybrid materials while conserving the electronic properties of the chromophore. Thus, they are powerful candidates for use in dye-sensitized solar cells.
