Copolymers based on 1, 4-diethoxybenzene (DEB) and 3, 4-ethylenedioxythiophene (EDOT) were electrochemically synthesized and characterized. The structures of the copolymers were established by 1H NMR and FT-IR spectroscopy. The results indicated the final product was a copolymer instead of a blend or a composite. The physical properties were systematically investigated by cyclic voltammetry, UV-vis absorption and fluorescence. The PL maximum of copolymers presented obviously red-shift to long wavelength as the feed ratio of EDOT in monomer mixture increased.

Polymerization of p-chloroaniline (CA) was achieved electrochemically in aqueous solution containing H2SO4 as supporting electrolyte. The films were obtained by applying sequential linear potential scan rate 20mV/s between -0.5 to 1.5V versus Ag/AgCl electrode. The polymer was characterized by UV-visible and FT-IR spectroscopy. We observed the morphologies of PCA films through the scanning electronic microscope (SEM), showing island protruding structure. The Tafel curves showed that PCA can be used as anti-corrosion material.

In this work, we report carbon-silicon bond formation in thiophene, assisted with alkylated silylchloride. The formylation reaction of silylated thiophene has been discussed and achieved 61% overall yield of reactions. The compounds obtained are characterized quantitatively and qualitatively by using elemental analysis, FT-IR spectroscopy, UV/Visible spectroscopy, and proton NMR spectroscopy. This research work will boost chemists to make the carbon-silicon bond and utilize them in various applications. Journal of Engineering Science 11(1), 2020, 101-105
