摘　　要：双重发射过渡金属配合物可以同时展现出两个最大发射波长,它结合了双重发射与过渡金属配合物发光材料的双重优势,在待测物的分析检测与成像领域具有重要的研究价值与应用前景.相较于单重发射金属配合物,基于双重发射金属配合物的比率发光探针,可以有效减少环境的干扰并显著提高分析检测的灵敏度和准确性.本文简述了双重发射金属配合物(主要包括钌、铂、铱等配合物)的设计策略及其在分子氧、金属离子和生物大分子的比率发光检测方面的应用,并阐述了双重发射金属配合物的研究现状和存在的问题,为今后双重发射金属配合物的合成和应用提供参考与借鉴.Dual-emissive transition-metal complexes can display two emission bands at distinctly different wavelength.They have the double advantages of being dual-emissive materials and photofunctional transition-metal complexes.They are useful in a wide range of applications such as ratiometric photoluminescent probes and bio-imaging.Compared to metal complexes with a single emission band,ratiometric photoluminescent probes based on dual-emissive complexes could effectively decrease the influence induced by the fluctuation of excitation energy and environment effects,and thus improve the sensitivity and accuracy.This review briefly summarizes the design strategies for the synthesis of dualemissive transition-metal complexes,in particular ruthenium,iridium,and platinum complexes,and their applications as ratiometric photoluminescent probes.In addition,the current challenges in the studies of dual-emissive transition-metal complexes are discussed,which is of interest and importance to the synthesis and applications of new dual-emissive molecular materials in the future.
