Recently varieties of Bodipy derivatives showing intersystem crossing (ISC) have been reported as triplet photosensitizers, and the application of these compounds in photocatalysis, photodynamic therapy (PDT), and photon upconversion are promising. In this review we summarized the recent development in the area of Bodipy-derived triplet photosensitizers and discussed the molecular structural factors that enhance the ISC ability. The compounds are introduced based on their ISC mechanisms, which include the heavy atom effect, exciton coupling, charge recombination (CR)-induced ISC, using a spin converter and radical enhanced ISC. Some transition metal complexes containing Bodipy chromophores are also discussed. The applications of these new triplet photosensitizers in photodynamic therapy, photocatalysis, and photon upconversion are briefly commented on. We believe the study of new triplet photosensitizers and the application of these novel materials in the abovementioned areas will be blooming.

最近，已报道了多种具有系间窜越（ISC）特性的Bodipy衍生物作为三线态光敏剂，这些化合物在光催化、光动力疗法（PDT）和光子上转换中的应用前景广阔。在本综述中，我们总结了Bodipy衍生的三线态光敏剂领域的最新进展，并讨论了增强ISC能力的分子结构因素。根据其ISC机制介绍了这些化合物，包括重原子效应、激子耦合、电荷复合（CR）诱导的ISC、使用自旋转换器和自由基增强的ISC。还讨论了一些含有Bodipy发色团的过渡金属配合物。简要评述了这些新型三线态光敏剂在光动力疗法、光催化和光子上转换中的应用。我们相信新型三线态光敏剂的研究以及这些新型材料在上述领域的应用将会蓬勃发展。
