Abstract
The studies of (TEMPO)3O3P molecules (tri‐(2,2,6,6‐tetramethyl‐1‐oxyl‐4‐piperidyl) phosphite) and their monolayers formed on highly oriented pyrolytic graphite (HOPG) are presented. (TEMPO)3O3P is synthesized from TEMPOL precursor (4‐hydroxy‐2,2,6,6‐tetramethylpiperidine‐1‐oxyl). We focused on electron paramagnetic resonance (EPR) and scanning tunnelling microscopy (STM) investigations. The EPR experiments demonstrate the paramagnetism of (TEMPO)3O3P in powdered form and in solution. Furthermore, these paramagnetic properties of (TEMPO)3O3P are preserved after the deposition on HOPG substrate. The STM studies show that (TEMPO)3O3P molecules have a strong tendency to form self‐assembled monolayers (SAMs). The detailed STM images let us to explore the structure of (TEMPO)3O3P on HOPG and propose a structural model for the observed SAMs. Copyright © 2013 John Wiley & Sons, Ltd.
