Abstract Three nanohybrid materials (FCSiPc@PEG-Cu-Cy) using poly (ethylene glycol) copper-cysteamine (PEG-Cu-Cy) nanoparticles as a carrier to load three fluorocoumarin silicon(IV) phthalocyanines (FCSiPcs) were prepared. The morphologies of these nanohybrids were characterized by transmission electron microscopy (TEM). The interactions between PEG-Cu-Cy nanoparticles and three FCSiPcs were studied by UV/Vis and fluorescence spectroscopic methods. The photophysical and photochemical properties of these FCSiPcs were influenced by PEG-Cu-Cy nanoparticles and exhibited substituents dependent of phthalocyanines in nanohybrids. The fluorescence resonance energy transfer (FRET) occurred from FCSiPcs (donors) to PEG-Cu-Cy nanoparticles (acceptors). These nanohybrids may be potential photosensitizers for photodynamic therapy.

封装氟香豆素硅（IV）酞菁的铜-半胱胺纳米颗粒：合成、表征和光物理特性

摘要 制备了三种以聚乙二醇半胱胺铜（PEG-Cu-Cy）纳米粒子为载体负载三种氟香豆素硅（IV）酞菁（FCSiPcs）的纳米杂化材料（FCSiPc@PEG-Cu-Cy）。这些纳米杂化物的形态通过透射电子显微镜（TEM）表征。通过紫外/可见光和荧光光谱方法研究了 PEG-Cu-Cy 纳米颗粒与三种 FCSiPcs 之间的相互作用。这些 FCSiPcs 的光物理和光化学性质受 PEG-Cu-Cy 纳米粒子的影响，并在纳米杂化物中表现出依赖于酞菁的取代基。荧光共振能量转移 (FRET) 从 FCSiPcs（供体）发生到 PEG-Cu-Cy 纳米颗粒（受体）。这些纳米杂化物可能是光动力疗法的潜在光敏剂。图形概要
