Title:
HIGH TRANSPARENCY ELECTROCHROMIC POLYMERS
Document Type and Number:
Japanese Patent JP2023116422
Kind Code:
A
Abstract:
To provide a new type of electrochromic polymers comprising meta-conjugated linkers and aromatic moieties, which present high transparency in the visible light region in a neutral state.SOLUTION: An electrochromic polymer comprises a repeat unit comprising one or more meta-conjugated linkers (MCLs) and one or more aromatic moieties (Ars). Each of the one or more MCLs is partially conjugated with the one or more Ars at meta positions of the MCLs to form a polymer main chain of the electrochromic polymer. The electrochromic polymer undergoes optical switching and color change in an electrochromic device, where the electrochromic device shows high transparency and high optical contrast.SELECTED DRAWING: None
