Irreversible photoisomerization behavior of 2-stilbazole ? covalently bound to porphyrin
Sugimoto, Hiroshi,Kuramoto, Keigo,Inoue, Shohei
, p. 1826 - 1830 (2002)
Irreversible cis-to-trans photoisomerization behavior was observed for a stilbazole-porphyrin (1), and its zinc complex (2). trans-1 and trans-2 did not isomerize to the corresponding cis-isomer under irradiation with UV light, although stilbazoles readily undergo the trans-to-cis isomerization upon UV irradiation. In contrast, cis-to-trans photoisomerization was observed for both cis-1 and cis-2; the isomerization of cis-stilbazole readily proceeds by visible light irradiation via complexation with metalloporphyrins.
Synthesis and Chromophoric Interactions of an 'ortho-Gable-porphyrin'. A Novel Tetraphenylporphyrin Dimer

A newly synthesized 'ortho-gable-porphyrin', a tetraphenylporphyrin-type dimer with an ortho-phenylene bridge, provided a model for closer porphyrin-porphyrin separation.

We present a straightforward and generally applicable synthesis route for cofacially linked homo- and heterobimetallic porphyrin complexes. The protocol allows the synthesis of unsymmetrical aryl-based meso-meso as well as β-meso-linked porphyrins. Our method significantly increases the overall yield for the published compound known as o-phenylene-bisporphyrin (OBBP) by a factor of 6.8. Besides the synthesis of 16 novel homobimetallic complexes containing MnIII, FeIII, NiII, CuII, ZnII, and PdII, we achieved the first single-crystal X-ray structure of an unsymmetrical cofacial benzene-linked porphyrin dimer containing both planar-chiral enantiomers of a NiII2 complex. Additionally, this new methodology allows access to heterobimetallic complexes such as the FeIII-NiII containing carbon monoxide dehydrogenase active site analogue. The isolated species were investigated by various techniques, including ion mobility spectrometry, DFT calculations, and UV/Vis spectroscopy. This allowed us to probe the influence of interplane distance on Soret band splitting.
PORPHYRINS AND THEIR DERIVATIVES XII. SYNTHESIS OF ISOMERIC FORMYLPHENYLPORPHYRINS
Ishkov, Yu. V.,Zhilina, Z. I.
, p. 1156 - 1160 (2007/10/02)
Isomeric mono(o-, m-, p-cyanophenyl)triphenylporphyrins were synthesized by the condensation of a mixture of aldehydes (benzaldehyde-cyanobenzaldehyde, 4:1) with pyrrole in xylene in the presence of monochloroactic acid.Reduction of the para and meta isomers of the zinc complex of cyanoporphyrin with sodium triethoxyaluminohydride in THF and of the ortho isomer by aluminum hydride gives the corresponding formyl derivatives.
