A series of D–A′–π–A type photosensitizers, AP3 and AP4, were designed and synthesized to show strong aggregation-induced far red and near infrared emission and very effective ¹O₂ generation simultaneously. In comparison with the most widely used photosensitizer, Ce6 nanoparticles, AP4 nanoparticles showed over 10-fold higher fluorescence quantum yield, and more than 3-fold higher ¹O₂ generation efficiency, and have been successfully used for image-guided photodynamic anticancer therapy.

具有聚集诱导发射的高性能光敏剂，用于图像引导的光动力抗癌治疗

设计并合成了一系列D–A'–π–A型光敏剂AP3和AP4，以显示强聚集诱导的远红和近红外发射以及同时非常有效的¹ O ₂生成。与最广泛使用的光敏剂Ce6纳米颗粒相比，AP4纳米颗粒的荧光量子产率高10倍以上，¹ O ₂生成效率高3倍以上，已成功用于图像引导的光动力抗癌治疗。
