Embodiment 1

[0040] (1) Synthesis of monomer EDOT-S:

[0041]Prepare a suspension from 0.38g (16mmol) of sodium hydride and 50mL of toluene. Under nitrogen protection, 2.24g (13mmol) of 3,4-ethylenedioxythiophene 2'-ethanol was added to the suspension, and heated to reflux for 1h. Then slowly add the prepared solution of 1.8g (13mmol) 1,4-butyl sultone and 15mL toluene through the dropping funnel, and continue heating to reflux for 2h. After cooling, 200 mL of acetone was added with vigorous stirring. The resulting suspension was filtered with a fine-pored glass funnel under nitrogen protection, and washed with acetone. Under vacuum drying at 100°C, 3.8 g of off-white powdery product monomer was produced.

[0042] Its structural characterization data are as follows:

[0043] Proton NMR spectrum: 1 H NMR (400MHz,D 2 O) δ6.43(q, J=3.6Hz, 2H), 4.36(d, J=6.4Hz, 1H), 4.21(dd, J=12.0, 2.1Hz, 1H), 4.03(dd, J=12.0, 6.8Hz,1H),3.72–3.63(m,2H),3.58–3.48(m,2H),2.87–2.81(m,2H),1.75–1.59(m,4H); ...

Abstract

The invention discloses a biological catalysis synthesis method of sodium polyethylenedioxythiophene sulfonate. The biological catalysis synthesis method is characterized by comprising the following steps: first, synthesizing a water-soluble monomer, namely, 3,4-ethylenedioxythiophene 2'-methoxybutyl sulfonate, and then catalyzing the water-soluble monomer, namely, 3,4-ethylenedioxythiophene 2'-methoxybutyl sulfonate by adopting a biological enzyme, thus synthesizing a water-soluble polyethylenedioxythiophene sulfonate compound, namely, poly3,4-ethylenedioxythiophene2'-methoxybutyl sulfonate. The sodium polyethylenedioxythiophene sulfonate obtained through the method provided by the invention can be directly dissolved in water, and no dopant is needed; compared with the existing commercial polyethylenedioxythiophene solution, the product prepared by adopting the method provided by the invention can be packaged into a solid commodity, so that the storage and transportation are facilitated, and meanwhile, a user can conveniently prepare solutions with different concentrations; the reaction conditions are mild, the conduction of the reaction can catalyzed at the room temperature or at a lower temperature, and a catalyst can be degraded after use, thus being an environment-friendly catalyst.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and relates to a method for synthesizing water-soluble polyethylenedioxythiophene, in particular to a poly(3,4-ethylenedioxythiophene 2'-methoxybutylsulfonate) with good water solubility. Biocatalytic synthesis of acid sodium salt. Background technique [0002] Polyethylenedioxythiophene (PEDOT) has good conductivity and stability, and has become a hot spot in the research of conductive polymers. important application. However, due to the conjugation of the rigid PEDOT main chain, it is difficult to process it into a film by dissolution or melting. The current general solution is to add a water-soluble polyelectrolyte - polystyrene sulfonic acid to the polymerization system. (PSS) was addressed as a charge-balancing dopant. The commercialized PEDOT / PSS compound obtained by this method is water-soluble and has good film-forming properties, but the PSS added reduces the conductivity of...
