CPL spectra (left) of both enantiomers of [Eu(bpcd)(tta)], with the normalized total luminescence spectrum overlaid, upon excitation at 365 nm. Eu(III) 5D0 luminescence decay curve (right) (the plot of the S,S isomer is shown and chosen as a representative). The equation of the fitting curve (red line) is y = 0.903 exp(−t/0.68) + 0.001 [reduced χ2 = 4.0 × 10–5; R2 (COD) = 0.99803].
