    pH-controlled self-assembling of meso-tetrakis(4-sulfonatophenyl)porphyrin-chitosan complexes

  • Original language description

    Solid meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS4-chitosan supramolecular complexes were prepared by addition of porphyrin to an aqueous solution of chitosan at pH values. The precipitates obtained were assigned as 1 (pH 6.8) and 2 (pH 2.5) and characterized by spectroscopic, thermal, and microscopic methods. Spectroscopic investigation confirmed the presence of TPPS4 and chitosan in both products and that the porphyrin is highly self-associated. Based on structural inferences, self-assembling hierarchy models were proposed for both of the TPPS4-chitosan supramolecular complexes.

    Hodnotami pH řízené spontánní uspořádání komplexů meso-tetrakis(4-sulfonatofenyl)porfyrin-chitosan

  • Czech description

    Supramolekulární komplexy meso-tetrakis(4-sulfonatofenyl)porfyrin (TPPS4)-chitosan v pevném stavu byly připraveny přidáním porfyrinu do vodného roztoku chitosanu při odlišném pH. Získané precipitáty byly označeny jako 1 (pH 6,8) a 2 (pH 2,5), a charakterizovány spektroskopickými, termálními a mikroskopickými metodami. Spektroskopické zkoumání potvrdilo přítomnost TPPS4 a chitosanu v obou produktech, jakož i vysoký stupeň asociace porfyrinu. Na základě strukturních závěrů byly navrženy modely hierarchiespontánního uspořádání pro oba supramolekulární komplexy TPPS4-chitosan.
