    • note
    • 2+ is very weakly emissive and the triplet lifetime, measured by transient absorption spectroscopy, has been reported as 250 ps in water, see ref. [32] while values of 565 ps, see ref. [13] or ca. 1 ns, see ref. [38b] have been found in acetonitrile. The fast rate of radiationless deactivation is attributed, in part, to mixing between the MLCT triplet and a metal-centered state lying at higher energy. At 77 K, the triplet lifetime increases to ca. 10 μs, see ref. [13];
