Abstract:
Tetraphenylporphyrin derivatives a synthetic heterocycles with convenient preparation and a richness of properties which make them attractive in broad fields such as energy, life and materials sciences. Thus, in the quest for new radical architectures, tetraphenylporphyrins are prime candidates. To this end, we designed free-base tetraphenylporphyrins bearing nitronyl and imino nitroxide moieties covalently bonded to the para-position of the meso-phenyl substituent. Their detailed synthesis and characterization are reported here.

Abstract:
The title compound, [Fe2(C44H28N4O)2O], was obtained as a by-product during the synthesis of FeIII tetraphenylporphyrin perchlorate. It crystallizes as a new polymorphic modification in addition to the orthorhombic form previously reported [Hoffman et al. (1972). J. Am. Chem. Soc. 94, 3620–3626; Swepston & Ibers (1985) Acta Cryst.

Abstract:
The synthesis of three novel axial dinucleosides was successfully accomplished. The compounds are 5″- O , 5″- O -dithymidylphosphorus(V)-meso-tetraphenylporphyrin, 5″- O , 3″- O -dithymi-dylphosphorus(V)-meso-tetraphenylporphyrin, and 3″- O , 3″- O -dithymidylphosphorus(V)tetraphenylporo-phyrin. These compounds could provide a lead toward the synthesis of an oligo-porphyrinyl DNA analogue that represents a system containing phosphorus(V)porphine units axially connected through the 5″- O -thymidine-3″- O bridges.

Abstract:
With the objective of developing an antitumor agent, the synthesis of a chromenopyrazoledione conjugated to a tetraphenylporphyrin is described. A complete conformational analysis of the novel porphyrin conjugate was performed using ab initio Hartree–Fock calculations at the 6-31G* level. The novel conjugate (14) shows stronger absorption intensity for both Soret and Q-bands than the free meso-tetraphenylporphyrin. It binds weakly but selectively to the cannabinoid receptor type-2. During the synthetic approach, a new tetraphenylporphyrin, 5-[4-(3,5-dioxomorpholino)phenyl]-10,15,20-triphenylpo

Abstract:
A meso-tetra-6b,10b-dihydrobenzo[j]cyclobut[a]acenaphthylene free-base porphyrin was synthesised and its photophysical, photochemical and electrochemical properties were compared with those of free-base meso-tetraphenylporphyrin. The frontier orbitals and the HOMO–LUMO energy gaps of both compounds were also determined. It was demonstrated that the meso6b,10b-Dihydrobenzo[j]cyclobut[a]acenaphthylene porphyrin retained the same properties as the tetraphenylporphyrin.

Abstract:
Irradiation by a high-pressure mercury arc of a mixture containing pyrrole, benzaldehyde, and Fe(III) in the medium of glacial acetic acid results in the formation of Fe(III)-meso-tetraphenylporphyrin and some amount of free meso-tetraphenylporphyrin. The products were identified by means of ESR and absorption spectra. When irradiated for long periods of time, the products undergo photochemical degradation. Since the photochemical incorporation of Fe(III) into the free meso-tetraphenylporphyrin ligand yields a complex with a structure different from that in the previous case, it may be conclud

Several cationic beta-vinyl-pyridinium and beta-vinyl-quinolinium-meso-tetraphenylporphyrin derivatives were synthesized starting from 2-formyl-meso-tetraphenylporphyrin, and the corresponding Zn(II) complex, and different N-alkyl derivatives of 2- and 4-methylpyridine and 2- and 4-methylquinoline. The new compounds were obtained in a one-step process via base catalyzed aldol-type condensation reactions. Electrospray ionization mass spectrometry (ESI-MS) and ultraviolet-visible (UV-vis) spectroscopy were used to investigate the binding mode of the synthesized cationic beta-vinyl-pyridinium and
