Introduction of fluorinated substituents onto the meso-phenyl groups results in enhancement of the luminescence properties of all three series of 5d metallocorroles: ReO, OsN, and Au. Luminescence decay times in solution were determined on the same spectrometer with the DeltaHub module (Horiba Scientific) controlling a SpectraLED-456 lamp (λ = 456 nm) and using DAS-6 analysis software for data analysis.
