Structures and properties of hemiquinone-substituted oxoporphyrinogens

  title={Structures and properties of hemiquinone-substituted oxoporphyrinogens},
  author={Jonathan P. Hill and Katsuhiko Ariga and Francis D'Souza},
The structure and physical properties of a series of N-substituted, hemiquinone-substituted oxoporphyrinogens is presented and discussed. Structures of the compounds are dictated by the nature of the substituent, with the substitution pattern being in turn dictated by regioselectivity of N-alkylation. X-ray crystallography and other aggregation properties of the compounds are discussed. Redox reactions are also strongly influenced by N-substitution and substituent identity. Also presented are… CONTINUE READING
