Abstract

Electrochemical properties of novel α,β -unsaturated ester compounds bearing 2,2,6,6-
tetramethylpiperidine-N-oxyl were studied. Synthesis of the compounds were realized with
basic aldehydes and malonic acid by Knoevenagel-Doebner reaction followed by the
esterification of the compounds with 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxy by
Steglich reactions with high yields. Also, poly(2,2,6,6-tetrametylpiperidine-N-oxy-4-yl 3-
(thiophene-3-yl)acrylate) synthesis and characterization are given. Afterwards, electrochemical
properties were studied by cyclic voltammetry in order to determine the diffusion coefficient
(Do) and standard electron-transfer rate coefficients (ko).
