摘要：
We describe the synthesis of beta-fluorinated porpholactones by oxidation of the fluorinated C=C bond of the pyrrolic subunit in porphyrin using the "RuCl3 + Oxone (R)" protocol. The electron-withdrawing effects of beta-fluorine on the absorption, fluorescence, phosphorescence and redox properties of the beta-fluoroporpholactones were studied. A potential application of the beta-fluoroporpholactones was demonstrated in sensitizing near-IR (NIR) emissive ytterbium, giving a high quantum yield (58%) and long luminescence time (525 mu s) in CD2Cl2.
