“…To determine the amount of catalyst in the polymer composition, an atomic adsorption analysis of the catalytically obtained sample was carried out in both doped ( PCo1 ) and undoped ( PCo1n ) forms. PCo1 treatment with an alkaline solution was carried out to establish the presence of a bond between the catalyst and the polymer chain, since phthalocyanines are highly soluble in alkali . In this process, the unbound cobalt phthalocyanine dissolved and an undoped PCo1n was obtained.…”

Effect of Cobalt Phthalocyanine on Synthesis and Physicochemical Properties of Polyaniline

2019

View full text Add to dashboard Cite

Organic transition metal complexes are successfully used in polymerization due to their catalytic activity in oxidative reactions. Here, polyaniline was synthesized with cobalt phthalocyanine as catalysts for the aniline oxidative polymerization. The conditions for obtaining polyaniline significantly affect the final product and the introduction of the component into the reaction mixture leads to a change in the physicochemical properties of the polymer. Thus, the effect of the catalyst on the polymer chain was determined using FTIR, UV‐visible spectral methods and atomic adsorption analysis. Electrical conductivity, thermal stability, electrochemical parameters (HOMO‐LUMO, band gap), surface morphology, and fluorescence emission spectra were estimated for the polymer samples obtained. The study of synthesized polymeric materials resulted that the use of cobalt phthalocyanines in the aniline oxidative polymerization process leads to better physicochemical properties, namely electrical conductivity, band gap and fluorescence quantum yield.

Self-association of sulfo derivatives of cobalt phthalocyanine in aqueous solution

et al. 2014

View full text Add to dashboard Cite

Sulfo derivatives of cobalt phthalocyanine containing naphthalene fragments have been synthesized, and their self-association and molecular complexation with pyridine in aqueous solution have been studied by spectrophotometry. The dissociation constants of the dimeric associates have been determined. The effects of the number of functional groups in the peripheral substituents and of the axial ligand on the phthalocyanine dimerization process have been revealed.

Self-association of sulfo derivatives of cobalt phthalocyaninates in the presence of 1,4-diazabicyclo[2.2.2]octane

et al. 2015

View full text Add to dashboard Cite

Complex formation between water-soluble cobalt(II) phthalocyaninates and 1,4-diazabicyclo[2.2.2]octane has been studied. The formation of the 1 : 1 molecular complex and the 2 : 1 sandwich-type dimers has been confirmed. The sandwich-type dimers and the J-aggregates involving the peripheral groups of the macrocycle are formed in ethanol medium. Stability constants of the molecular complexes have been determined, and the effect of size of the peripheral substituents on the dimeric structures stability has been elucidated.
