摘要 三重态-三重态湮灭(TTA)上转换具有所需激发光能量低(地表太阳光光强即可激发)、上转换量子效率高、吸光能力强、激发发射波长可调等优点,在光电器件与光反应等领域具有重要的潜在应用价值,近年来受到了广泛关注.本文介绍了TTA上转换产生的机理与上转换量子效率的测定方法,着重对TTA上转换三重态光敏剂的分子设计原则及目前该类化合物的结构类型进行了综述,介绍了聚合物中的固态上转换现象及目前TTA上转换在光解水制氢、太阳能电池与细胞成像等方面的最新应用研究进展. Triplet-triplet annihilation （TTA） has attracted much attention due to its requirement of low excitation power density （solar light is sufficient）, high upconversion quantum yield, readily tunable excitation/emission wavelength and potential applications in photovoltaics and photocatalysis, etc. This review introduced the mechanism of TTA upconversion and method for calculation of upconversion quantum yield, as well as the design rationales of the reported sensitizers were reviewed in detail. Photo upconversions in rubbery polymeric materials and polymer nanoparticles and applications in fields like photoelectrochemistry, solar cells, bioimaging in vivo were also reviewed.
