Problems solved by technology

[0003] CN102482569A discloses a blue or green neutral state that is soluble and shows oxidation to a transmission state to be used as an alternating donor-acceptor polymer for electrochromic polymers, but the green polymers obtained in this invention cannot Directly and effectively adjust the blue light absorption intensity in the short wavelength region (400-490nm) and the red light absorption intensity in the long wavelength region (560-750nm)
[0004] In the prior art, the preparation of green electrochromic polymers is hindered by complex monomer synthesis and lack of simple and efficient absorption spectrum tuning methods
And there is no simple and effective way to adjust the absorption of polymers in the visible light region.

Abstract

The invention provides a green electrochromism macromolecule material as well as a preparation method and application thereof. The green electrochromism macromolecule material has a structure as shownin a formula I; a thiophene derivative monomer, a 2,1,3-diazosulfide monomer and a fluorene-containing derivative monomer structure are simultaneously introduced in the structure, and the monomer structures meet the proportion relation in a polymer, so that a macromolecule absorption spectrum can be effectively adjusted, and a green macromolecule compound is obtained; the preparation method is simple and high efficient, the material can be obtained through one-step polymerization of three to four monomers, and multiple green macromolecules with fine differences can be conveniently obtained through changing the relative proportion of the four different monomers, so that the green electrochromism macromolecule material has an excellent electrochromism performance, can be applied to multipletechnical fields of intelligent color-change windows, display screens, intelligent color-change thin films, field effect transistors, organic solar cells, super-capacitors and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a green electrochromic polymer material and its preparation method and application. Background technique [0002] Electrochromic polymers have received more and more attention due to their application prospects in flexible displays, smart windows, and data storage. Among the existing electrochromic polymers, red and blue polymers are the most numerous. Since green electrochromic polymers (Pierre M. et al. Spray Processable Green to Highly Transmissive Electrochromics via Chemically Polymerizable Donor–Acceptor Heterocyclic Pentamers. Adv. Mater. 2008, 20, 2772–2776) need to simultaneously absorb the short wavelength region (400-490nm ) blue light and red light in the long wavelength region (560-750nm), such double absorption band characteristics make the design and synthesis of green electrochromic polymers always a difficult point. [0003] CN102482569A discloses a blue or green...
