虽然环化配合物已被广泛研究的光电应用，这些化合物也代表了一个相对较新的一类光敏剂的单线态氧的生产。到目前为止，单线态氧的产生从环化的Ir和Pt配合物进行了详细的研究。在这篇综述中，单重态氧的产生从这些配合物的电子物理数据，和1O2生成的机制进行了讨论，包括单重态氧的产生通过电子转移机制的一些环化的Ir配合物的证据。从2002年到2013年8月的第一次报告的单重态氧产生的环化铱配合物的期间涵盖在本次审查。这类新的单线态氧光敏剂可能被证明是相当通用的，由于辅助配体的取代而不损失活性。几种环化的配合物已经被束缚到沸石、聚苯乙烯或量子点上。介绍了光氧化在有机分子中的应用，包括传统的单线态氧反应（烯反应，[4+2]和[2+2]环加成）以及胺的氧化偶联。潜在的生物医学应用也进行了审查。
While cyclometalated complexes have been extensively studied for optoelectronic applications, these compounds also represent a relatively new class of photosensitizers for the production of singlet oxygen. Thus far, singlet oxygen generation from cyclometalated Ir and Pt complexes has been studied in detail. In this review, photophysical data for singlet oxygen generation from these complexes is presented, and the mechanism of 1O2 generation is discussed, including evidence for singlet oxygen generation via an electron transfer mechanism for some of cyclometalated Ir complexes. The period from the first report of singlet oxygen generation by a cyclometalated Ir complex in 2002 through August 2013 is covered in this review. This new class of singlet oxygen photosensitizers may prove to be rather versatile due to the ease of substitution of ancillary ligands without loss of activity. Several cyclometalated complexes have been tethered to zeolites, polystyrene, or quantum dots. Applications for photooxygenation of organic molecules, including “traditional” singlet oxygen reactions (ene reaction, [4+2] and [2+2] cycloadditions) as well as oxidative coupling of amines are presented. Potential biomedical applications are also reviewed.
