“…EC polymer employs the redox effect of monomers with functional groups to modify the electronic structure of polymers. [58][59][60] The main EC polymers are organic conjugated polymers, transition metal coordination polymers, etc. When an electric field is applied, the ions in the polymer are moved, which causes a redox reaction in the polymer, resulting in a reversible change in the color of the material.…”

Electrochromic devices (ECDs) possess the performance advantages in terms of color adjustability, low power consumption, and visual friendliness, emerging as one of the ideal candidates for energy‐efficient smart windows, next‐generation displays, and wearable electronics. The optical and electrical characteristics of ECDs could be adjusted by modifying the materials or structure of devices. This review summarizes the recent developments of innovative technologies and key materials of ECDs for display applications, highlighting the key issues and the development trends in this area.

“…Many efforts have been made to cover a wider color gamut, for example, by material design, [192] the development of a new mechanism, [63] the use of color overlays, [2,193] and mix-and-match strategies. [3,194] However, the fabrication complexity and resulting low-quality colors of the electrochromic materials and devices still challenge researchers and limit advanced applications. Here, inspired by the various brilliant structural colors obtained using optical resonators (Section 3.2), we describe a fascinating approach, the combination of electrochromic materials with optical resonators, which has excellent potential for overcoming these limitations.…”

With rapid advances in optoelectronics, electrochromic materials and devices have received tremendous attentions from both industry and academia for their strong potentials in wearable and portable electronics, displays/billboards, adaptive camouflage, tunable optics, and intelligent devices, etc. However, conventional electrochromic materials and devices typically present some serious limitations such as undesirable dull colors, and long switching time, hindering their deeper development. Optical resonators have been proven to be the most powerful platform for providing strong optical confinement and controllable light–matter interactions. They generate locally enhanced electromagnetic near‐fields that can convert small refractive index changes in electrochromic materials into high‐contrast color variations, enabling multicolor or even panchromatic tuning of electrochromic materials. Here, resonant‐cavity‐enhanced electrochromic materials and devices, an advanced and emerging trend in electrochromics, are reviewed. In this review, we will focus on the progress in multicolor electrochromic materials and devices based on different types of optical resonators and their advanced and emerging applications, including multichromatic displays, adaptive visible camouflage, visualized energy storage, and applications of multispectral tunability. Among these topics, principles of optical resonators, related materials/devices and multicolor electrochromic properties are comprehensively discussed and summarized. Finally, the challenges and prospects for resonant‐cavity‐enhanced electrochromic materials and devices are presented. We believe this review will definitely promote the communications among optical physics, electrochemistry, and material science.This article is protected by copyright. All rights reserved

“…A deeper understanding of the principles of the modulation of infrared light by the TMOs will be benecial for effectively improving the ability to regulate emissivity and establish relationships between the material design and performance optimization. For organic electrochromic materials, it mainly includes organic small molecules 50 (such as viologen 51 ), transition metal-ligand complexes (such as metal-organic frameworks (MOFs) [52][53][54] ) and conjugated polymers (poly(3,4ethylenedioxythiophene) (PEDOT), [55][56][57] polypyrrole (PPy), 58 polyaniline (PANI) 59,60 and polyindole 61 ). In terms of the electrochromic performance of conjugated polymers, they present high coloration efficiency, large color contrasts, rapid response times, and low power consumption during the operation.…”
