Sonochemical Activation of Hematoporphyrin: An ESR Study

The production of 2,2,6,6-tetramethyl-4-piperidone-N-oxyl by reaction of 2,2,6,6-tetramethyl-4-piperidone (TMPone) with ultrasonically generated active species in oxygenated solutions of hematoporphyrin (Hp) was studied by electron spin resonance spectroscopy. The nitroxide production rate in air-sa...
