Herein, we evaluated the intersystem crossing quantum yield (Φ_ISC) of a silicon phthalocyanine derivatized from IRDye700DX (IR700) which is used as a photosensitizer for photoimmunotherapy (PIT), using fluorescence correlation spectroscopy (FCS). The calculated Φ_ISC was 0.019 ± 0.002. The FCS measurement was validated by experiment in the presence of potassium iodide, which can change the kinetics of the relaxation process in the excited state.

荧光相关光谱法分析光敏剂光免疫疗法的三重态动力学

在本文中，我们评估了间跨越量子产率（Φ _ISC从IRDye700DX（IR700）衍生化的硅酞菁，其被用作用于光免疫（PIT）光敏剂的），使用荧光相关光谱（FCS）。所计算出的Φ _ISC为0.019±0.002。通过在碘化钾存在下的实验验证了FCS的测量，碘化钾可以改变激发态下弛豫过程的动力学。
