“Phenylpicrylhydrazyl” on n-type Oxidic Surfaces

Nature volume 214, pages 1108–1109 (1967)Cite this article

Abstract

MANY organic compounds have a relatively stable electron spin resonance signal1–6 even at room temperature when adsorbed on a surface. In all these cases, the radical is a positive ion formed as a result of charge transfer with an appropriate site on the adsorbent. Recently, we have found that 1-phenyl-2-picrylhydrazine adsorbed on an anatase sample of high area shows an electron spin resonance signal. The line shape, colour and chemistry of the adsorbed species strongly indicate that it is a phenylpicrylhydrazyl free radical and we wish to report here certain preliminary qualitative electron spin resonance results and its chemistry on oxidic surfaces.
