Synthesis and characterization of tetranitro and tetraamino zinc phthalocyanines and their combinations with mica-titania pigment

Sönmez, Yasemin
In the present study, tetranitro and tetraamino substituted zinc phthalocyanine were synthesized by using nitro phthalic acid precursor under microwave irradiation. The products were purified using different solvents. Molecular structures of these phthalocyanine pigments were confirmed by FT-IR and UV-visible spectroscopy analyses. Each of these pigments was settled on the surface mica-titania pigment to obtain ‘combination pigment’. Tetraamino zinc phthalocyanine was deposited on mica-titania in water and in dimethyl formamide used as solvent, while tetranitro zinc phthalocyanine was deposited in chloroform. The pH effect was investigated by using acetic acid and trifluoro acetic acid. The conditions for optimum deposition time, solvent, pH and the amount of phthalocyanine were studied. The FT-IR, XPS and elemental analysis were conducted to analyze the pigment deposited on the vi surface of the mica-titania substrate. Moreover, the fluorescence properties of tetranitro and tetraamino zinc phthalocyanines and their combinations by mica-titania pigment were obtained in DMF solvent. The surface morphology of synthesized pigments was analyzed by scanning electron microscopy (SEM). The paint samples of these pigments were prepared by water based styrene acrylic resin formulation. The L*a*b* color properties of the pigments were examined by color spectrophotometer. These analyses indicated that pigments were successfully synthesized and combined with mica-titania pigment. The best result with tetranitro zinc phthalocyanine was obtained in chloroform solvent at 50°C, in 5h, and at a pH of 5; while the best result with tetraamino zinc phthalocyanine in DMF with acetic acid at 120°C, in 3h and at a pH of 4. The amount deposited increased with the amount of phthalocyanines in solution. Mica-titania substrate reduced the fluorescence of phthalocyanine pigments. But on the other side, the fluorescent property of the mica-titania were developed with combination of tetra amino and nitro phthalocyanines. It was observed that, with the increasing amount of tetranitro and tetraamino zinc phthalocyanine, the deposited amount of pigment increased on mica-titania, as well. As a result high gloss fluorescent

In the present work, titanate nanoribbons were synthesized by hydrothermal route using P25 (Degussa) TiO2 powder as precursor and strong NaOH as catalyzer. The prepared titanates were calcined followed by protonation. Powders were characterized using Field Emission Scanning Electron Microscope (FESEM), High Resolution Electron Microscope (HRTEM), X-Ray diffraction Analysis (XRD), Differential Thermal Analysis and UV-Vis Photospectroscopy. Methylene blue degradation test was applied to evaluate the photoacti...

Buyukyagci, Arzu; Tuzcu, Goezde; Aras, Leyla (Elsevier BV, 2009-07-01)
Water-soluble copolymers of methoxy polyethylene glycol acrylate (mPEGA) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were synthesized by free radicalic polymerization and evaluated as slump-retaining dispersant for cement particles. The slump-retaining effect of the synthesized copolymers was studied in terms of reaction pH, composition, and molecular weight of mPEG side chains. mPEG grafted copolymers (mPEGA-co-AMPS) were characterized by FTIR, H-1 NMR. In this study, dilute solution viscometry...

A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(perfluorophenyl)-2,5-di(2-thienyl)-1H-pyrrole (FPTPy). The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1-NMR) and fourier transform infrared (FTIR). Polymer of FPTPy was also synthesized via potentiostatic electrochemical polymerization in acetonitrile (AN)/NaClO4/LiClO4 (0.1 M:0.1 M) Solvent-electrolyte couple. Characterizations of th...

Synthesis of a series of new conjugated electrochromic polymeric pyridinium salts containing main-chain triphenylamine and their electrochromic properties were demonstrated. All polymers exhibit intense UV absorptions at 336-338 nm in DMF and 340-343 nm in thin film form and fluorescence centered at 410-438 nm in DMF and 460-461 nm in thin film form. The electrochromic properties of the films were investigated by electrochemical and spectroelectrochemical methods. Reversible redox signals with stable electr...
