Paper Abstract

Some pophyrins as molecular materials are discussed in this paper. Aggregates of these molecules have been known for some time to possess interesting properties. Their optical properties as isolated species in condensed phases have also recently become interesting, and their ability to form new hybrid materials, by mixing them with themselves or other molecules with different electron affinities and ionization potentials, now appears to be extremely attractive. Few porphyrin structures, 5,10,15,20-tetra-p-phenyl-porphyrin (TPP), 5,10,15,20-tetra-p-methoxy-phenyl-porphyrin (TMOPP), 5,10,15,20-tetra-p-tolyl-porphyrin (TTP), 5,10,15,20-tetra-p-sulphonato-phenyl-porphyrin (TSPP), have been synthesized in this paper. Some analytical investigations as UV-Vis spectrophotometry (UV-Vis), Fourier transformed infrared spectroscopy (FTIR), atomic force microscopy (AFM) have been discussed as purity and stability criteria. Also, some considerations about their aggregation ability are discussed, and not in the last time, their capacity to generate porphyrin nanotubes.
