Abstract
Two pyrene dimers containing an -O-Si-Si-O- or -O-Si-O- linkage have been designed which exhibit ratiometric excimer/monomer emission upon fluoride anion induced Si-O bond cleavage. Incorporation of the probe into water soluble polymeric nanoparticles enhances its intracellular uptake and displays ratiometric fluorescent sensing for F(-) in living cells.
摘要
两种含有-O-Si-Si-O-或-O-Si-O-键的芘二聚体被设计出来，它们在氟阴离子诱导的 Si-O 键断裂后表现出比率型的激基缔合物/单体发射。将探针掺入水溶性聚合物纳米粒子中，增强了其细胞内摄取，并在活细胞中对 F(-)进行了比率型荧光传感。
