A new phthalonitrile (1) was synthesized and characterized using different spectroscopic techniques, elemental analyses, single-crystal X-ray diffractometry. The crystal structure is stabilized by p-p stacking interactions between the benzene rings with two methyl groups. Metal free (2), Mg (3), Zn (4), Pd (5) phthalocyanine complexes of were metal salts, showed good solubility in a wide range organic solvents no aggregation observed within concentration range. UV-Vis, FT-IR, NMR, mass...
A series of novel asymmetric metallo (Mg, Zn and Ga) phthalocyanines were synthesized using different ratios starting materials. After purification, these compounds obtained in high yields. The characterized by ultraviolet-visible (UV–vis), infrared (IR) 1H NMR spectroscopy, mass spectrometry (MS) elemental analysis. High solubility organic solvents was observed because the ester moiety at peripheral position, no aggregation over a wide concentration range. photophysicochemical properties...
This research concentrates on the preparation, characterization, and photoluminescence properties of saccharide conjugated copper phthalocyanine (CuPc) its metal-free precursor (H2Pc). The H2Pc ligand gave intense emissions (where λmax = 701 nm) upon irradiation by visible light. quantum yields long excited-state lifetimes these compounds were measured. has yield 0.42 lifetime 3.89 ns. intensities decreased dramatically complexation with metal derivatization groups.
Abstract This work details the preparation and characterization of a tetracarboxyzinc phthalocyanine (ZnTCPc) immobilized onto silica gel coated with gold nanometal (Au@SiO2) investigates its photocatalytic activity for first time. The immobilization ZnTCPc on Au@SiO 2 surface was performed through pre‐anchorage cysteine (CSH) via post‐synthesis method, then conjugated to (Au@SiO ) an amide bond obtain heterogeneous photocatalyst (ZnTCPc−Au@SiO ). prepared (ZnTCPc‐Au@SiO were characterized...
