A series of tetraphenylethylene-porphyrin conjugates(1-3) were newly synthesized with Rothemund-Lindsey condensation and Fischer method. Compounds were characterized by UV-Vis absorption, fluorescence spectroscopy, Mass spectrometry, 1H-NMR and cyclic voltammetry. In UV-Vis spectra, results showed that each compound’s soret band and two Q bands were slightly red-shifted as TPE substituents increases. The fluorescence emission was also red-shifted, due to the increasing electron donation properties of TPE groups on meso-positions. Each compound’s HOMO-LUMO energies were also calculated by converting the redox potentials acquired by cyclic voltammetry in which compound 3 showed cathodic shift of first oxidation potential value. We herein discuss in detail photophysical properties of tetraphenylethylene-Porphyrin conjugates. |
