Description	Three tetracationic porphyrins differing in the position of the charged nitrogen atoms on the peripheral substituents - 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)porphyrin (TMPyP4), 5,10,15,20-tetrakis(N-methylpyridinium-2-yl)porphyrin (TMPyP2), 5,10,15,20-tetrakis(4-trimethylammoniophenyl)porphyrin (TMAPP), and hydrophobic 5,10,15,20-tetraphenylporphyrin (TPP) were immobilized by adsorption and encapsulation in poly(hydroxymethylsiloxane) (PHOMS). 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.
