Mesoporous organosilica-porphyrin composites were obtained by entrapment of 5,10,15,20-tetrakis(1-methyl-4-pyridinio)porphyrin (TMPyP) and 5,10,15,20-tetraphenylporphyrin (TPP) into three polysilsesquioxanes prepared by sol-gel method from 1,2-bis(triethoxysilyl)ethane, 1,6-bis(triethoxysilyl)hexane, and 1,8-bis(triethoxysilyl)octane. The materials were characterized by their texture and optical properties (fluorescence and absorbance) and by light-induced antimicrobial activity against E. coli BL21(DE3) (pET16bDsRed) strain.
