β-Fluorinated porpholactones and metal complexes: synthesis, characterization and some spectroscopic studies

Abstract

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.
