overview | 3,4-ethylene dioxythiophene (EDOP) is a colorless to light yellow transparent oily liquid with an atmospheric boiling point of 225 ℃. it is one of the monomers for preparing poly 3,4-ethylene dioxythiophene (PEDOP). its preparation mainly uses quinoline as solvent, copper powder as catalyst, reactant 2,5-dicarboxylic acid -3, 4-ethylene dioxythiophene is heated to above 180 ℃ in solvent for decarboxylation reaction. This method has high reaction temperature, low product yield and serious environmental pollution. |
application | 3, 4-ethylene dioxythiophenol can be used to synthesize polythiophenol or oligothiophenol organic electroactive materials such as organic conductive polymer materials, photoelectric materials, etc. |
preparation | under the condition of nitrogen protection, add 50g of 2,5-dicarboxylic acid -3,4-ethylene dioxythiophene and 250 ml of dimethyl sulfoxide (DMSO) to 500 ml of three-mouth flask, fully stir to dissolve the solid, then add 4g of copper powder, then raise the temperature to 160 ℃, and react for 9 hours, TLC detects that the raw materials are completely reacted and then cooled to room temperature, the catalyst is filtered away, the filtrate is washed with water, extracted, separated with liquid, dried with organic phase, and concentrated to obtain red-brown oily liquid. Decompression is rectified, and the fraction at 128-132 ℃ is collected to obtain light yellow oily liquid 21g, which is 3,4-ethylene dioxythiophene. GC analysis content is 99.5% (area naturalization method), and the yield is 68%. |
use | application is mainly used to synthesize conductive polymer PEDT, which is widely used in modern electronics industry. Used as a reducing agent in synthetic gold nanoparticles; starting material for palladium-catalyzed arylation reaction; used in the synthesis of coupling polymers and copolymerics, used as a synthetic conductive polymer PEDT. Used for the synthesis of conjugated polymers and copolymers; used as a reducing agent when synthesizing gold nanoparticles by HAuCl4 one-pot method; used as a raw material for palladium-catalyzed mono-and bis-arylation reactions; used for conductive polymers Monomer |
