The porphyrin-PHOMS composites so prepared were characterized by porosimetry, scanning electron microscopy, fluorescence, and diffuse reflectance UV-vis spectroscopy. It was found that porphyrins are immobilized in PHOMS matrix in the free base monomer form. Their irradiation produced singlet oxygen O2(1Δg) with a lifetime of 10-30 microsecunde.
