We describe the synthesis of β-fluorinated porpholactones by oxidation of the fluorinated C [double bond, length as m-dash]

C bond of the pyrrolic subunit in porphyrin using the “RuCl₃ + Oxone®” protocol. The electron-withdrawing effects of β-fluorine on the absorption, fluorescence, phosphorescence and redox properties of the β-fluoroporpholactones were studied. A potential application of the β-fluoroporpholactones was demonstrated in sensitizing near-IR (NIR) emissive ytterbium, giving a high quantum yield (58%) and long luminescence time (525 μs) in CD₂Cl₂.

β-氟代内酯和金属配合物：合成，表征和一些光谱学研究

我们描述了 [双键，长度为m-破折号]

使用“ RuCl ₃ +Oxone®”方案，通过氧化卟啉中吡咯亚基的氟化C C键来合成β-氟化卟啉内酯。研究了β-氟对β-氟卟啉内酯的吸收，荧光，磷光和氧化还原性质的吸电子作用。证明了β-氟代内酯在将近红外（NIR）发光致敏方面的潜在应用，可在CD ₂ Cl _2中提供高量子产率（58％）和长发光时间（525μs）。
