摘　　要：由于在生物领域和物联网领域的广泛应用,化学传感器在近期发展迅速.相比于纯有机分子的荧光化学传感器,基于重金属配合物的磷光化学传感器由于发光寿命长,斯托克斯位移大等优点越来越引起人们的广泛关注.重金属铱配合物三线态寿命短,发光效率高而且配合物的发射波长容易受配体的改变而发生变化,因此成为最好的磷光传感器材料之一.本文介绍了铱配合物在磷光化学传感器领域中的应用,具体包括:阳离子传感器、阴离子传感器、氧分子传感器、氨基酸传感器、pH传感器等,并指出了相比于其它磷光化学传感器,基于铱配合物的磷光化学传感器的优势以及目前所存在的问题,最后,对基于铱配合物的磷光化学传感器的研究和发展方向进行了展望.Chemosensors have developed quickly because they are widely used in biology. Compared to organic fluorescent chemosensors, phosphorescent chemosensors based on heavy metal complexes have attracted great attention because of distinctive merits such as relatively long lifetimes and significant Stokes shifts. Iridium complexes had been successfully used as phosphorescent chemosensors because of their relatively short excited state lifetime, high photoluminescence efficiency, and wide range emission colors that can be tuned by the coordinated ligands. In this review, we have summarized the applications of iridium complexes in cation, anion, oxygen, amino acid, and pH sensors. Furthermore, the advantages and disadvantages of these chemosensors have been compared to others. Finally, some prospects for future study are proposed.
