Abstract
Molecules of Mg-tetracarboxyphthalocyanine, chemically modified with 3-aminopropyltrimethoxysilane, were immobilized on the surface of the nanopores in a silicate gel matrix by copolymerizing them with tetraethoxysilane monomer. Formation of covalent bonds between the Mg-phthalocyanine molecules and the surface of the nanopores in the silicate xerogel was confirmed by the absence of leaching of the “grafted” pigment from the interior volume of the xerogel to the liquid extraction agent, and also by IR Fourier spectroscopy data. The observed bleaching of the activated silicate xerogel under normal atmospheric conditions is reversible: subsequent heat treatment restores the original absorption spectrum. We hypothesize that two mechanisms are responsible for the observed effect: formation of high order associates of the Mg-phthalocyanine molecules involving water molecules adsorbed from the atmosphere, and/or oxidation of the phthalocyanine macrocycle with disruption of the conjugation chain.
