Influence of the Nature of the Nitrogen-Containing Base on the Kinetic Stability of Tetra(1,2,5-thiadiazolo)porphyrazine in Dimethyl Sulfoxide

详细

The state of tetrakis(1,2,5-thiadizole)porphyrazine in the DMSO medium was studied. The protontransfer complex that formed was found to be quite stable. This complex was shown to decompose in some strong base solutions after some delay. The influence of either the nature of nitrogen-containing base and NH acidity of the porphyrazine macrocycle on the destruction kinetics of proton-transfer tetrakis(1,2,5-thiadizole)-porphyrazine complexes was investigated.
