摘要:
A novel unsymmetrical porphyrin meso-5-(p-octanoyloxyphenyl)-10,15,20-triPhenylporphyrin (OPTPPH2) and relative transition metal complexes (DPTPPM, M = Zn, Fe, Co, Ni, Cu, Mn) were synthesized and characterized by elemental analysis, UV-Vis spectra, mass spectra, H-1 NMR, infrared spectra, Raman spectra, and cyclic voltammetry. In dimethylformamide (DMF), 0.1 mol.L-1 tetrabutylammonium perchlorate (TBAP), these compounds exhibit two or three one-electron reversible redox reactions. Quantum yields of the S-1 center dot S-0 fluorescence are measured at room temperature. These studies will contribute to further choice and application of the liquid crystals.
