The main results are as follows.1. The UV-visible absorption spectra, the spin-trapping EPR measurements, and the DPA (9,10-diphenylanthracene) bleaching experiments showed that (1) HB-Net exhibits much improved light harvesting efficiency in the phototherapeutic window (600-900 nm) as the result of its remarkable absorption red shift with respect to HB;(2) HB-Net remains the generation abilities of semiquinone anion radical, superoxide anion radical, hydroxyl radical, and singlet oxygen, but with much lower efficiencies than that of HB, most likely due to its very short triplet excited state lifetime.

设计合成了寡聚吡咯酰胺修饰的竹红菌乙素衍生物HB-Net，利用紫外-可见吸收光谱、自旋捕获技术和DPA光漂白法详尽比较了HB-Net与HB的光动力性质，发现：(1) HB-Net的吸收光谱较HB有显著红移，在光疗窗口的吸光能力明显提高；(2) HB-Net能够产生半醌负离子自由基、超氧负离子自由基、羟基自由基和单重态氧，但由于其短的三重态寿命，这些活性物种的产生能力均弱于HB.2。
