Functional metallomacrocycles and their polymers, Part 37.

Preparation of a thermosensitive cobalt phthalocyanine/N-isopropylacrylamide copolymer and its catalytic activity on thiol

“…Metallophthalocyanines (MtPc) have attracted considerable attention as oxidation catalysts because of tetra N -donor macrocyclic structural similarity to the naturally occurring metalloporphyrins, their chemical and thermal stability, and their rather cheap and easy preparation on a large scale [1][2][3][4][5][6], whereas they have the following problems: low solubility, high aggregation tendency, and difficulty in catalyst recovery and recycling [7,8]. Strategies of immobilizing MtPc on multifarious insoluble supports, such as zeolites, activated charcoal, and clays, have been introduced to prepare polymeric phthalocyanine catalysts, facilitate catalyst separation and recycling, and reduce effluent contamination [9][10][11][12][13].…”

Unusual kinetic role of a water‐soluble iron(III) porphyrin catalyst in the oxidation of 2,4,6‐trichlorophenol by hydrogen peroxide

“…These methods usually use H 2 O 2 or KHSO 5 as the stoichiometric oxidant and iron complexes as catalysts. The most successful reported catalysts have ligands with a set of four N-donor atoms in either a planar or nonplanar geometry [1][2][3][4][5][6]9,12,13]. In addition to H 2 O 2 -dependent oxidation, TiO 2 -based systems for photodegradation [8,10,11,14] and ozonization [7] have also been thoroughly studied.…”

Synthesis and selected properties of metallo and metal-free 2,3,9,10,16,17,23,24 –octacarboxyphthalocyanines

“…The presence of such a polymer improves solubility of phthalocyanine, creates a propitious micro environment which surrounds the phthalocyanine catalyst and also prevents the inactive aggregates. 68 Photochemical properties include singlet-oxygen quantum yield (  ) and photodegradation, whereas photophysical properties include fluorescence lifetimes and triplet state quantum yields ( T ) and lifetimes ( T ). 3 The photochemical properties of phthalocyanines are tested in regard to their possible use in photodynamic therapy (PDT).…”
