Abstract

Abstract This minireview discusses recent advances in transition metal complexes for electrochromic (EC) and electrofluorochromic (EFC) devices. EC and EFC materials can switch their color and photoluminescence, respectively, through electrochemical redox reactions. Transition metal complexes offer promising opportunities due to their molecular design versatility for various optoelectrical properties. The review provides an overview of electrochromism and electrofluorochromism, including performance characterization methods and device fabrication techniques. It highlights EC transition metal complexes that can form thin films suitable for device applications and EFC transition metal complexes that can efficiently tune photoluminescence through electrochemical quenching mechanisms. The review also summarizes advanced functions of EC/EFC transition metal complexes, including large optical contrast, fast response, dual-switching of color and emission, and easy device fabrication, which could lead to low-cost displays. Overall, this review article presents the latest research on transition metal complexes for EC and EFC devices and their potential for practical applications.

电致变色和电致荧光器件的过渡金属配合物

摘要本文综述了用于电致变色（EC）和电氟变色（EFC）器件的过渡金属配合物的最新进展。EC和EFC材料可以通过电化学氧化还原反应分别切换其颜色和光致发光。过渡金属配合物由于其分子设计对各种光电性质的多功能性而提供了有希望的机会。综述了电致变色和电氟变色，包括性能表征方法和器件制造技术。它强调了可以形成适合器件应用的薄膜的EC过渡金属络合物和可以通过电化学猝灭机制有效调节光致发光的EFC过渡金属络合物。综述了EC/EFC过渡金属配合物的先进功能，包括大的光学对比度、快速响应、颜色和发射的双重切换以及易于制造的器件，这些都可能导致低成本的显示器。总之，这篇综述文章介绍了用于EC和EFC器件的过渡金属配合物的最新研究及其实际应用潜力。

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
