Decay-associated spectra (DAS) of two-component mixture of fluorophores for W-Me-β-CD host-guest complex (25 μM for W, and 1 mM for W-Me-β-CD) at pH 3 (A) and pH 9 (B) and upon excitation at 320 nm and room temperature. The corresponding steady-state spectra of each solution are also shown for comparison (see experimental section).
