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.
