摘　　要：三重态光敏剂在光催化领域的应用日益广泛,而传统的稀有金属配合物光催化剂存在着吸光能力弱、三重态寿命短、经济性差等短板,限制了该类光敏剂的进一步应用。因此,亟需开发出新型的具有强可见光吸收和长三重态寿命的三重态光敏剂。简要介绍三重态光敏剂参与的光催化体系的光化学基础理论以及基本催化过程,综述近年来氟硼吡咯类(BODIPY)光敏剂在光催化有机合成和光催化产氢领域的研究进展,并对今后的三重态光敏剂作为光催化剂的发展做出展望。Triplet photosensitizers are widely used in photocatalysis.The conventional photosensitizers based on precious metal complexes were limited in further applications due to the weak absorption of visible light,short triplet excited state lifetimes and the high cost.Therefore,it is important to develop novel triplet photosensitizers with strong absorption of visible light and long triplet excited state lifetime.This review briefly introduces the photochemical basic theories and catalysis process of photocatalysis involving triplet photosensitizers.We also introduce the recent progress on BODIPY as triplet photosensitizer in photocatalytic synthetic organic reactions and photocatalytic hydrogen evolution.Finally,we further clarify the development expectation of triplet photosensitizers on photocatalysis.
