Fractional fluorescence quantum yield (ϕ) values of compounds 1 and 2 in the presence of 20 equiv of ZnCl2 in water/CH3CN mixture (1:1) containing HEPES (25 mm) and NaCl (25 mm) at pH 7.3 determined within different spectral windows. Green: 415–800 nm; blue: 450–550 nm; red: 500–530 nm. The values determined within the green window equate the actual fluorescence quantum yields of the zinc(II) complexes.
