Novel Co(II) phthalocyanines of extended periphery and their water-soluble derivatives. Synthesis, spectral properties and catalytic activity

Silica nanoparticles were obtained during the work according to two different sol–gel methods. In first one Schtrober's technique and series of cobalt phthalocyanine metal complexes varying in peripheral substituents were used. Second method was performed using the same complexes but differed in applying surface‐active substance (SAS) and two precursors – tetraethoxysilane (TEOS) and aminopropyltrimethoxysilane (APTMOS). All obtained hybrid materials were analyzed via SEM, the size of single particle was studied, which in all cases was about 200 nm. In order to investigate hybrid's characteristics laser diffraction and liquid nitrogen adsorption methods were applied. Distinction in pore's specific volume of differently‐obtained nanoparticles was found. Catalytic activity of all obtained materials were tested in conversion of N,N‐diethylcarbamodithiolate to thiuram E. Effect of peripherally substituted phthalocyanines and morphology of matrixes were manifested on catalytic activity of the hybrids.

“…On the basis of the previously described method, [33] 4-[4-(1-methyl-1-phenylethyl)phenoxy]-5-nitrophthalonitrile was synthesized by nucleophilic aromatic substitution of the bromine atom for the 4-(1-methyl-1-phenylethyl) phenol residue in 4-bromo-5-nitrophthalonitrile (Scheme 1). The reaction was carried out in aqueous DMF in the presence of potassium carbonate at room temperature for 0.5 hour.…”

Bifunctional substituted copper and nickel phthalocyanines were synthesized. These compounds were modified by introduction of sulfonic and sulfonamide groups into aryloxy fragments. Spectral and mesomorphic properties of synthesized compounds were studied.Keywords: Bifunctional substituted phthalocyanines, synthesis, mesomorphism. 2,9,16,23-тетра(1-бензотриазолил)-3,10,17,24-тетра[4-(1-метил-1-фенилэтил)фенокси] фталоцианина меди на нитрогруппы приводит к неспособности данного производного фталоцианина формировать мезофазу как при нагревании, так и в различных растворителях.

The work reports catalytic properties of series of cobalt phthalocyanines peripherally substituted with consistently changing sulfonated fragments. Data on heterogenization of cobalt phthalocyaninates onto organic and inorganic polymers are provided. Comparing catalytic activity of the macrocycles in dependence on structure and peripheral substituent as well as polymer carrier's type is given. Application of cobalt phthalocyanine's sulfonic acids for fine synthesis of thiuram E upon both homogeneous and heterogeneous catalysis is shown to be prospective.
