Catalytic properties of polymer matrix-immobilized cobalt complexes with sulfonated phthalocyanines

A new water-soluble sulfonated cobalt(II) phthalocyanines: Synthesis, spectral, coordination and catalytic properties

“…Previously the kinetics and mechanism of that process in the presence of homogeneous and heterogeneous phthalocyanine catalysts were investigated in our works [8,29,34,36]. We showed that structure of macrocycle and its coordination ability play the main role in catalysis.…”

“…Besides the geometrical factor has a big influence on monomerization of metallophthalocyanine in solution. Earlier [15,29] we found that addition of monodentate ligand (pyridine, piperidine) to solutions of cobalt phthalocyanine sulfonic derivatives that have sulfonic groups connected by naphthalene fragments (analogs of CoTSPc1 and CoTSPc2 without benzotriazole fragments) leads to dissociation of H-aggregates and formation of monoligand axial complexes in solution. Pyridine and piperidine have no second donor atom.…”

Catalytic properties of cobalt complexes with tetrapyrazino porphyrazine and phthalocyanine derivatives

“…To determine the current SDC concentration, samples 2 mL in volume were taken at specific time intervals throughout each experiment. The procedure for analytical spectrophotometric esti mates of a current SDC concentration was described in [27,28].…”

The Surface Modification of the Polypropylene by Aqueous Soluble CoII Phthalocyanine to Obtain Materials for Catalysis

“…[32,33] Previously, when using the same materials, we have shown that [34] in the visible region of CoPc's UV-Vis there are two intense absorption bands: corresponding to the associated state of the macrocycle (630 nm) and its monomer form (665 nm) (Figure 1). This fact allows us to control spectrally aggregation of the macrocycle that is important for immobilization.…”
