Electrochromic Two-dimensional Covalent Organic Framework with a Reversible Dark-to-transparent Switch

Abstract

Electrochromic(EC) materials with a dark-to-transmissive switch have potential applications in optical communications, infrared wavelength detectors for spacecraft, and infrared camouflage coatings. Recently, Yu et al. proposed an innovative low-voltage dark-to-transparent switchable electrochrome based on a donor-acceptor two-dimensional covalent organic framework(COF) material. The compound can be facilely processed in a large-area thin film, which allows for the wide applications in smart displays, windows, and clothing. This work has been published online in Nature Communications on November 2nd, 2020.
