Inspired by biochemical reactions, a new electrochromic mechanism was proposed based on metal-ligand interactions for color conversion of dyes. The system combines electrochemical stability of metal ions with color adjustability of dyes, achieving high transmittance change and broad color tunability in EC devices.
Inspired by the dynamic coordination and dissociation between metal ions and ligands involved in biochemical reactions, we proposed and explored in detail a new electrochromic (EC) mechanism, based on the color conversion of dyes induced by electrical adjustable metal-ligand interactions. Different from the traditional EC materials, whose color-changing motifs and redox motifs are located at the same site, this new material is an indirect-redox-color-changing system composed by switchable dyes and multivalent metal ion. These EC devices combine the advantages of electrochemical stability of metal ions and the color adjustability of readily available dyes with high molar absorption coefficient, high transmittance change (74%), broad color tunability, and good coloration efficiency (506.67 cm(2)/C). A prototype of see-through EC reader with high white light contrast ratio (8.5:1) has been achieved based on dynamic metal-ligand interactions. More importantly, the new application of dynamic metal-ligand interactions might induce more pleasant surprise in other areas.

A Strategy of Stabilization via Active Energy-Exchange for Bistable Electrochromic Displays

Chang Gu, Xiaojun Wang, Ai-Bo Jia, Hongzhi Zheng, Weiran Zhang, Yuyang Wang, Minjie Li, Yu-Mo Zhang, Sean Xiao-An Zhang

Summary: This article introduces a new strategy based on proton-coupled electron transfer for actively adjusting the energy levels of materials to achieve bistability from traditional nonbistable materials. By studying quinone derivatives and bromocresol green derivatives, further polymerization and optimization can lead to outstanding bistability in devices with potential applications for energy-saving flexible displays. The success, challenges, and cognitive gains of this strategy not only accelerate the development of various energy-saving optoelectronic materials/devices, but also have the potential to stimulate progress in physics, chemistry, and materials.
