Method for detection or determination of molecular oxygen by EPR spectrometry employing radical lithium phthalocyanines and a composition which can be used for in-vivo determination. …<??>This method consists in… - bringing into contact with the said medium a radical lithium phthalocyanine corresponding to the formula: …<IMAGE>… in which R<2>, R<3>, R<6>, R<7>, R<1><0>, R<1><1>, R<1><4> and R<1><5> denote a hydrogen atom, a deuterium atom or a C1-C3 alkyl or alkoxy radical, and R<1>, R<4>, R<5>, R<8>, R<9>, R<1><2>, R<1><3> and R<1><6> denote a hydrogen or deuterium atom, on condition that R<1> to R<1><6> do not all denote a hydrogen atom, and… - examining the EPR signal of the radical lithium phthalocyanine in contact with the said medium. |
