Molecularly imprinted poly (4, 4′-methylenedianiline) as electrochemical sensor for determination of 1-benzothiophene

Self-cross linked poly (4.4′-methylenedianiline) as a conductive polymer was prepared via oxidative polymerization of 4.4′-methylenedianiline. Synthesis of poly 4.4′-methylenedianiline in acidic condition, leads to formation of phenazine structural units. Molecularly imprinted poly 4.4′-methylenedianiline, synthesized using 1-benzothiophene as template. The π-π stacking effect between 4.4′-methylenedianiline and 1-benzothiophene, made the compact imprinted polymer and more imprinted sites. Field emission scanning electron microscopy, FT-IR spectroscopy, X-ray diffraction and differential scanning calorimetry were used to characterize the morphology and structure of the poly- (4.4′-methylenedianiline). Detection of 1-benzothiophene was performed with molecularly imprinted poly- (4.4′-methylenedianiline) modified electrode. Cyclic voltammetry was used to character the molecular imprinted polymer and nonimprinted polymer.
