Synthesis and catalytic properties of hybrid materials based on organically modified silica matrix with cobalt phthalocyanine

A Comparative Study of Catalytic Activity of Fe, Mn and Cu Porphyrins Immobilized on Mesoporous MCM-41 in Oxidation of Sulfides

“…In order to improve the catalytic performance of the MPc or metalloporphyrin, numerous support materials have been employed. [4][5][6][7][8] Metalloporphyrins have been investigated extensively for biomimetic oxidation of organic compounds as models of cytochrome P450s due to their innate properties, and also because of existence in many natural and fundamental products. [9][10][11][12] These metallo-complexes are able to catalyze selective oxidation processes with a variety of oxygen donors.…”

Sulfonated octa‐substituted Co(II) phthalocyanines immobilized on silica matrix as catalyst for Thiuram E synthesis

“…Hybrid materials were synthesized and purified according to Stobber's method. TEOS:H 2 O:C 2 H 5 OH – 1:4.5:10 molar ratio was used for synthetic procedure . Triethylamine of 0.35 ml as a polycondensation catalyst was added dropwise into reaction mixture each 10 minutes after the homogenization of reaction mixture.…”

“…Triethylamine of 0.35 ml as a polycondensation catalyst was added dropwise into reaction mixture each 10 minutes after the homogenization of reaction mixture. Purification and calculation non‐entrenched substance were performed according to the method …”

“…Moreover, dissolved metal phthalocyanines aggregate affecting catalysis and first of all the selectivity of catalyst significantly. The possible way to avoid aggregation of phthalocyanines metal complex is immobilization of the compound on organic or inorganic polymer matrixes . Graphene, carbon nanotubes, polymer oxides of, for example, silicon, titanium, zirconium are the most prospective solid‐phase carriers.…”

Symmetrical and difunctional substituted cobalt phthalocyanines with benzoic acids fragments: Synthesis and catalytic activity

“…Catalysts obtained by immobilization of metallophthalocyanines on solid-phase carriers, carbon nanotubes, organic polymers are also perspective [8][9][10]. Carbon residues of phthalocyanine molecule may be used as anchoring groups for linking with biological molecules containing fragments of primary amines [11], immobilization on polymer surface, for example silica [12] or nanotubes [13] that may be used to create novel materials for purposes mentioned above.…”
