Different Micellar Packing and Hydrophobicity of the Membrane Probes TEMPO and TEMPOL Influence Their Partition Between Aqueous and Micellar Phases Rather than Location in the Micelle Interior

We report the investigation of the distribution of two stable nitroxyl radicals, 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) and 4-hydroxy-TEMPO (TEMPOL), between aqueous and micellar phases and in the micelle interior by quenching of fluorescence of dipyridamole (DIP) and by1H NMR, ESR, and optica...
