Novel peripherally functionalized seco-porphyrazines: synthesis, characterization and spectroscopic evaluation Academic Article uri icon


  • Co-macrocyclizations of 2,3-dipropylmaleonitrile and 2,3-di-(4- (methoxycarbonyl)phenyl)maleonitrile, respectively, with N,N′-dibenzyl-N, N′-di-(11-tetrahydropyranyloxy-3,6,9-trioxo-undecyl))maleonitrile and N,N,N′,N′-tetramethylmaleonitrile were used to prepare derivatives of the 4,5-diamino-porphyrazine systems including the zinc(II) complexes. Subsequent oxidation of the macrocycles with potassium permanganate gave the corresponding seco-porphyrazines. These were shown to be efficient sensitizers for the production of singlet oxygen (ΦΔ=0.15-0.57) by the determination of their photophysical properties. © 2003 Published by Elsevier Ltd.
