Abstract
Synthetic routes to polyradicals are briefly reviewed; in addition the synthesis and electrochemical characterization of a novel 2,6,6-tetra methylpiperidinyloxy-1-pyrrylacetate(I) (or, TEMPO-1-pyrrylacetate) ar e reported. Rather than forming a conducting polymer deposit, this mon omer coats the electrode with a passivating monolayer, which is electr oactive at the nitroxide potential (+0.93 V vs Ag+/0). The cyclic volt ammetry of the surface-confined nitroxide not only exhibits typical mo nolayer behaviour (calculated coverage 0.5 nmol cm-2), but also unusua l spikes caused by trapped charge.
