by the reaction of 4-amino-2,5-dihydro-2,2,5,5-tetramethyl-1H-imidazol-1-oxyl with aminomethylated u,p-unsaturated carbonyl methiodides or hydrochlorides. Introduction of hydrophilic (COOH) or lipophilic (C 1 0 H 2 1 ) groups in the aminomethylated compounds allowed the synthesis of pH-sensitive spin probes with different solubilities.
