complex	τ_obs (ms)	τ_obs (ms), CD₃OD	τ_rad (ms)	ϕ_int (%)	ϕ_ovl (%)	η_sens (%)	m^b
[Eu(bpcd)(tta)]	0.68(1)	1.18(1)	2.38(1)	26.4(1)	26	100	1.3(5)^c
[Eu(bpcd)(Coum)]	0.80(1)	1.40(1)	2.42(1)	33.1(1)	7	21.1	1.1(5)^c

The reported values are the same for both enantiomers.

Number of methanol molecules in the inner coordination sphere.

Calculated as described in ref (50). Following the Judd–Ofelt theory,⁵⁶ one can calculate τ_rad from the emission spectra, only in the case of the Eu(III) ion.

Calculated by a modification for Tb(III) of the equation discussed for the Eu(III)⁵⁰ ion.
