Optically controlled distribution of o-quinonemethacrylate metal complexes in polymer materials
The complexation ability of photoreduction products of 2-(2,5-di-tert-butyl-3,4-dioxycyclohexa-1,5-dienyl)ethyl methacrylate in tetrahydrofuran (THF) solution and in its copolymer films with dimethacrylate and ethylene glycol monomethacrylate was studied. The product of photochemical reduction – catechol – reacts with (NH4)6Mo7O24·4H2O, NH4VO3 and (NH4)2Fe(SO4)2 with the formation of corresponding metal complexes in solution and in the polymer bulk. The concentration of the molybdenum complexes in the polymer matrix was proportional to the exposure and holding time in solution of molybdate salt. Polymer film with optically controlled distribution of o-quinonemethacrylate molybdenum complexes was prepared. A film containing antimony and molybdenum complexes together in the polymer structure in predetermined ratio was obtained by sequential treatment of irradiated copolymer film (50% conversion) by THF solution of SbPh3, and water solution of (NH4)6Mo7O24·4H2O.
