Recent exciting developments in the area of mononuclear photoactive complexes with Earth-abundant metal ions (Cu, Zr, Fe, Cr) for potential eco-friendly applications in (phosphorescent) organic light emitting diodes, in imaging and sensing systems, in dye-sensitized solar cells and as photocatalysts are presented. Challenges, in particular the extension of excited state lifetimes, and recent conceptual breakthroughs in substituting precious and rare-Earth metal ions (e.g. Ru, Ir, Pt, Au, Eu) in these applications by abundant ions are outlined with selected examples. Relevant fundamentals of photophysics and photochemistry are discussed first, followed by conceptual and instructive case studies.
本文介绍了在具有地球上储量丰富的金属离子（铜、锆、铁、铬）的单核光活性配合物领域取得的最新令人兴奋的进展，这些配合物在（磷光）有机发光二极管、成像和传感系统、染料敏化太阳能电池以及作为光催化剂方面具有潜在的环保应用。文中概述了面临的挑战，特别是激发态寿命的延长，以及通过大量离子取代这些应用中珍贵和稀土金属离子（如钌、铱、铂、金、铕）的近期概念性突破，并列举了一些实例。首先讨论了光物理和光化学的相关基本原理，随后是概念性和指导性的案例研究。
