(a) Zinc(II) coordination quenches the emission of compound 1 through photoinduced electron transfer (PET) from the excited anthryl to zinc(II)-bound bipy [40]. φ: fluorescence quantum yield. (b) Similarly, zinc(II) coordination also decreases the fluorescence quantum yields of compounds 2 and 3 [41,42].
