Synthesis of metal-free and metallophthalocyanines bearing a-methylferrocenylmethoxy units was described. Precursor 3 required for the preparation of phthalocyanines 4–9, was synthsized by the nucleophilic aromatic substitution reaction between a-methylferrocenylmethanol and 4-nitrophthalonitrile in dry DMF. The metal-free phthalocyanine 4 was prepared from 4-(amethylferrocenylmethoxy)phthaloni...

Three novel substituted zinc (II) phthalocyanines (one anionic, one cationic and one neutral) were compared to two clinically used photosensitizers, 5,10,15,20-tetra(m-hydroxyphenyl)chlorin (m-THPC) and polyhematoporphyrin (PHP), as potential agents for photodynamic therapy (PDT). Using the RIF-1 cell line, photodynamic efficacy was shown to be related to cellular uptake. The cationic phthalocy...

Monomeric (M 1⁄4 2Li or 2H) and polymeric (M 1⁄4 2H, Zn, Cu, Co, or Ni), where M is metal or hydrogen, phthalocyanines were prepared by the tetramerization reaction of bisphthalonitrile monomer with appropriate materials. The electrical conductivities of the polymeric phthalocyanines, which were measured as gold sandwiches, were found to be 10 –10 7 S/cm in vacuo and in air. The binding propert...

The sensitivities of metallophthalocyanine (MPcs: M = Co, Ni, Cu, Zn, and H(2)) chemiresistors to vapor phase electron donors were examined using 50 nm MPc films deposited on interdigitated electrodes. Sensor responses were measured as changes in current at constant voltage. Analytes were chosen to span a broad range of Lewis base and hydrogen bond base strengths. The MPc sensor responses were ...

Binding configurations, interface electronic structures, and magnetic properties of 3d transition-metal phthalocyanine (MPc, where M = Mn, Fe, Co, Ni, Cu or Zn) molecular systems on a Au(111) substrate are systematically investigated with first-principles density functional theory calculations using the Perdew-Wang (PW91) exchange-correlation functional. We also calculate the corresponding prop...

Conversion of CO2 into valuable compounds, including fuels, with renewable energy sources and sustainable compounds is a challenge addressed by artificial photosynthesis research. In particular, the application solar assisted electrochemical (EC) processes, in which electrons are furnished photovoltaic (PV) cell, promising approach. A PV-EC system described, consisting CIGS (copper indium galli...

Dopamine (DA) and uric acid (UA) are biomolecules of great consideration that coexist in human body. It is essential challenging to detect them simultaneously with high sensitivity. This paper reports a novel electrochemical biosensor based on the nanocomposites cobalt phthalocyanine (CoPc) anchored graphene quantum dots (GQDs) for DA UA detection. The GQDs incorporation CoPc nanorods partial e...

A practical method for organic–inorganic hybrid heterojunction photodetector by spin-coating the cobalt phthalocyanine (CoPc) solution onto ?-gallium oxide (?-Ga2O3) film is available to realize sensitive detection of ultraviolet light signals. We have carefully measured and calculated optoelectronic performance prepared device. The device demonstrates excellent rectification characteristics un...

An ethynyl-substituted nickel(II) phthalocyanine has been synthesised and its thermotropic properties studied; optical microscopy, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) techniques revealed an unusual mesomorphic behaviour observed for the first time in phthalocyanine systems where each disk of the hexagonal columnar mesophase is formed by two ethynyl-substituted ph...
