A porous Vycor glass (PVG)-attached porphyrin photosensitizer has been synthesized. A phenyl-urea linkage at the 5-position covalently bonds 10,15,20-triphenylporphyrin onto PVG. Investigations are underway to determine whether singlet oxygen is generated in aqueous solution upon irradiation of this PVG-based complex.
