Direct anodic oxidation of 1,2- methylenedioxybenzene (MDOB), one of the analogues of 3,4-alkylenedioxythiophene and 3,4-alkylenedioxypyrrole, led to the formation of a novel polyacetylene derivative poly(1,2-methylenedioxybenzene) (PMDOB) on a platinum sheet in acetonitrile with good fluorescence properties of emissions at 390 and 410 nm, together with the electrochromic property from sap green (doped) to baby blue (dedoped). IR, H-1 NMR, C-13 NMR and quantum chemistry calculations confirmed the polymerization occurred at the C-4 and C-5 position on the benzene ring of the monomer, making the main backbone of PMDOB similar to polyacetylene. SEM results indicated the formation of aligned PMDOB nanorod on the electrode surface. The pressed PMDOB pellet has a conductivity of 0.8 S cm(-1). To the best of our knowledge, this is the first report on the electrochemical polymerization of MDOB and characterization of its polymer.
