In this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (TNPP) and its zinc porphyrin complex (ZnTNPP) were synthesized in situ using the microwave method and identified by UV-Vis, FT-IR and 1H NMR. The photostability and photodynamic antimicrobial activity (PACT) of these compounds were investigated on Pseudomonas aeruginosa and Bacillus subtilis under visible light irradiation. MIC, MBC an...
