Abstract
The distribution of photoactive compounds (PACs) in polymer matrices impregnated in supercritical carbon dioxide (SC-CO2) was studied by fluorescence microscopy. The pattern of PAC distribution in polymers was shown to depend on the nature of the matrix, the degree of interaction between introduced PAC molecules and polymer fragments, and corresponding diffusion coefficients. Such information may be in demand for the design of functionally oriented polymer systems impregnated with PACs (heterogeneous catalysis, photochromic materials, and medicine).
