Immobilization of metallophthalocyanines on hybrid materials and in-situ synthesis of pseudo-tubular structures from an aminofunctionalized kaolinite

New strategies for synthesis and immobilization of methalophtalocyanines onto kaolinite: Preparation, characterization and chemical stability evaluation

“…Characterization of Ka and KaDMSO provided results that agreed with literature data and confirmed the lamellar nature of kaolinite and DMSO intercalation into the clay [10,17]. Both spectra displayed the typical bands of metallophthalocyanines: the Soret band between 300 and 350 nm and the Q band between 600 and 700 nm [3,4].…”

“…The procedures used to purify the clay mineral and to intercalate dimethylsulfoxide (DMSO) into its interlayer space were carried out as described in other literature articles authored by members of our research team [10,17].…”

“…To meet the principles of green chemistry and sustainability when synthesizing metallophthalocyanines, researchers have searched for new routes that demand less energy and little or no metal or metallic salt as the starting reactant. Another research activities aimed to improve the properties of metallophthalocyanines by immobilizing them on inorganic matrixes [10].…”

“…In this context, kaolinite has stood out for its natural abundance, physicochemical properties, and lamellar structure. Kaolinite constitutes an important industrial raw material for immobilization of metallophthalocyanines [10], porphyrins [14,15], and other complexes [16], to generate hybrid organic-inorganic materials with interesting properties.…”

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

“…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. Thus, investigations of phthalocyanine macrocycle structure expansion are actively continuing at the moment [14,15].…”
