Using glycine-induced nanoparticle to enhance photo-induced electron transfer efficiency in donor-acceptor system

The glycine moiety was introduced to the porphyrin-oxadiazole compound through the s-triazine group. Regular nanoparticles were assembled by the newly synthesized compound using surfactant-assistant self-assembly method. The morphology of nanoparticles was characterized by scanning electron microscopy and X-ray diffraction analysis. The photo-physical properties of both the monomer and nanostructure in solvent were characterized by UV-visible, steady-state and transient fluorescence spectra, indicating that the glycine moiety enhanced the efficiency of photo-induced electron transfer from excited porphyrin to oxadiazole module in the monomer and nanoparticle of the new dyad.
