Asymmetric phthalocyanines (A3B type) containing aminophenoxy and hydroxyphenyl-diazenyl-phenoxy substituents

In this research new asymmetric metal-phthalocyanine complexes (A3B-type), with Zn2+, Co2+ and Ru2+, bearing aminophenoxy and hydroxyphenyl-diazenyl-phenoxy substituents, were synthetized. The synthetic route to asymmetric Pcs (A3B-type), based on ring expansion method is refined. The photophysical and electrochemical properties of the new phthalocyanines were investigated. In addition to this investigation, a comparative study took place on the effect of the expansion of conjunction on properties of the MPc compound. Moreover, the effect of pH to the ground state electronic absorption spectra of compounds bearing hydroxyphenyl-diazenyl-phenoxy substituents was also studied. Theoretical studies (DFT) were also carried out in order to support the corresponding experimental results. © 2019 Elsevier B.V

Synthesis, characterization and theoretical studies of novel phthalocyanine complexes

A new class of metal-free and metallophthalocyanines (M = Zn, Cd) bearing 5,6-dihydro-1,4-dithiin-2,3-dithiole substituents on peripheral positions were synthesized and fully characterized. The electrochemical and photochemical properties of these compounds were investigated. DFT calculations were also performed and the results supported the corresponding experimental. © 2013 Elsevier B.V. All rights reserved

Synthesis, characterization and DFT analysis of new phthalocyanine complexes containing sulfur rich substituents

Nine new tetrasubstituted metallophthalocyanines (MPc) bearing sulfur rich substituents on peripheral positions were synthesized and fully characterized. The new MPc compounds contain Co2+, Ni2+ and Cu2+. The photochemical and electrochemical properties of the new molecules were investigated. In addition to this investigation, a comparative study took place on the effect of the type of terminal ligand on properties of the MPc compound. Theoretical studies (DFT) were, also carried out in order to support the corresponding experimental results. © 2019 Elsevier B.V
