摘要：

''Polyveratrole'' was synthesized by electrochemical oxidation of 1,2-dimethoxybenzene in acetonitrile/tetrabutylammonium tetrafluoroborate on a platinum electrode at 1.600 V vs. Ag/Ag+ (0.01M). Instantaneous formation of nuclei occurs followed by a randomly oriented unidimensional growth of green fibrils. The fibril growth that is related to a stacking structure of several ''monomer'' units of hexamethoxytriphenylene cation radicals associated with BF4- counterions. The process of nucleation and fibril growth is a periodic event that leads to the formation of a nest-like arrangement. As time increases, this arrangement lines up with the electric field, and the product exhibits paramagnetic properties. Ex situ reflectance Fourier transform infrared spectroscopy, and solid state nuclear magnetic resonance spectra confirm aromatic ring fusion. Calorimetric analysis of the green product shows that polyveratrole sublimes under vacuum at about 250 degrees C.
