3-BUTYLTHIOPHENE - Preparation Method
Open Data Verified Data
- chemical oxidative polymerization in a three-necked flask equipped with a stirrer and a thermometer, add the solvent nitrobenzene and the monomer 3-butylthiophene; Turn on the stirrer, A proportional amount of the oxidizing agent ferric chloride [(3-3.5):1] was further added, and the temperature was raised to carry out polymerization for 4-12 hours. The product was precipitated with methanol, washed, and dried to obtain a powdery product. When doping, it is first soaked in ethanol, adding iodine ethanol solution or ferric chloride solution, after a considerable period of time, washed with methanol, and then vacuum dried, the doped poly (3-butylthiophene) was obtained.
- electrochemical polymerization method in a single-chamber three-electrode electrochemical reaction cell with conductive glass as anode, aluminum sheet as cathode and Ag/AgCl as reference electrode, 0. 02mol/L tetrabutylhexafluorophosphoramide supporting electrolyte solution and 0. 20mol/L monomer 3 a butyl thiophene electrolyte solution, in the nitrogen protection, constant temperature 5 degrees Celsius, constant current density 6mA/Crf12 electrolytic polymerization in Min, to a film like product.
