Synthesis and Photoelectron Spectroscopy of Spin Labeled Metal Complexes

Abstract

(4) Two new spin labeled metal complexes; cobalt(II) bis(2,2,6,6-tetramethyl-1-oxyl-4-piperidyl p-salicylaldiminobenzoate) (3), copper(II) bis(2,2,6,6-tetramethyl-1-oxyl-4-piperidyl-p-salicylaldiminobenzoate) were prepared. The synthesis of amino derivatives of nitroxide compounds were improved by a simplified synthetic route. The XPS spectra of 3 and 4 were determined. The observed N Is, Cu 2p and Co 2p spectra of spin labeled metal complex are discussed.
