| titleOfInvention | High transmittance soluble electrochromic polymer from neutral violet to oxidized state |
| abstract | The invention discloses a neutral-state purple to oxidation-state high-transmittance soluble electrochromic polymer and a preparation method thereof, wherein different lengths of alkane side chains are adjusted, modified 3, 4-ethylenedioxythiophene derivative monomers and self-dibromo monomers are copolymerized through direct arylation coupling polycondensation, and the color-changing color of the polymer is further regulated and controlled by adjusting the pi conjugation degree and the energy band structure of the polymer, so that the transition from purple to transparent is realized. The introduction of the side chain realizes the solubility of the polymer. The polymer provided by the invention has electrochromic application potential and solution processing characteristics, the material has high ionic conductivity, and a large number of electrolyte ions are rapidly diffused into the polymer material to balance charges after voltage is applied, so that the color change speed of the material is accelerated, the response rate of the material is improved, and the contrast is improved. |
