(a) Fluorescence spectra of 1 in water/ACN (1:1) solution (D ≈ 1.7·10−6 M) as a function of [Zn2+]. The arrow indicates decreasing [Zn2+]. (b) Relative change in fluorescence intensity F / F0 at 460 nm as a function of [Zn2+] for 1 in water/ACN (1:1) solution (D ≈ 1.7·10−6 M). The solid line corresponds to the best fit by eq. (5). The absolute accuracy of each experimental point is ± 10%.
