organic radical lithium phthalocyanine 2020-05-22T12:53:58Z LiPc Physicochemically lithium phthalocyanine is very stable; its response to pO2 does not change with conditions and environments (e.g., pH, temperature, redox conditions) likely to occur in viable biological systems. It is an organic radical compound that forms metallic-organic, paramagnetic crystallites that appear very useful for in vitro and in vivo electron paramagnetic resonance oximetry.
