Photophysical Characterization of Novel Neutral and Cationic Phthalocyanine-like Photodynamic Agents AbstractWe report on the photophysical properties of novel neutral and cationic
tetrapyridinoporphyrazines. These compounds are interesting as potential photosensitizers
for inactivation of bacteria. Neutral pyridinoporphyrazines show photophysical properties
comparable to those of typical metallophthalocyanines. The cationic derivatives are
partially aggregated in organic solvents, but can |
