(A) The dependence of fluorescence time course (λ_ex 320 nm, λ_em 400 nm) on [7]. Conditions: [1] = 5 mM, [Cu(OAc)₂·H₂O] = 10 µM, and [7] = 1–10 µM in CH₃OH at 25 °C. (B) Plot of lnV_int vs. ln[7]. The slope yields the kinetic order of 7. V_int: initial observed rate = d[8]/dt (M·s⁻¹). The spectra taken after 48 h, assuming full conversion, are included in Figure S6.
