Porphyrin molecule has extensive two-dimensional π-conjugated system, and it's assemblies have attracted considerable recent interests as photocatalyst and solar energy transduction materials due to their optical and electronic properties. Here we report the preparation of a naphthalene-bridged porphyrin oligomer and its self-assemblies induced by coordination with bidentate ligands (1,4-diazabicyclo[2.2.2]octane (DABCO), 4,4'-bipyridyl (Bipy)) in solution. The self-assembly process has been studied using UV-vis, FL and 1H NMR spectroscopy. To probe photophysical properties of porphyrin assemblies, spectroscopic measurements containing UV-vis absorbtion and emission spectra have been performed. |
