Fig. 3

a UV–vis absorption spectra of HA–BrBP, CB[7]/HA–BrBP, and CB[8]/HA–BrBP in aqueous solution at 25 °C ([BrBP] = 0.05 mM, [CB[7]] = 0.05 mM, [CB[8]] =  0.025 mM). b The Prompt photoluminescence spectra of HA–BrBP (0.5 mM) (black), HA–BrBP/N2 (red), CB[7]/HA–BrBP (light blue), CB[7]/HA–BrBP/N2 (pink), CB[8]/HA–BrBP (green), and CB[8]/HA–BrBP/N2 (wine) in aqueous solution at 25 °C. c The phosphorescence spectra of HA–BrBP, CB[7]/HA–BrBP, and CB[7]/HA–BrBP/N2 at 298 K in aqueous solution (delayed by 0.2 ms, Ex. Slit = 10 nm, Em. Slit = 10 nm). d The phosphorescence spectra of HA–BrBP, CB[8]/HA–BrBP, and CB[8]/HA–BrBP/N2 at 298 K in aqueous solution (delayed by 0.2 ms, Ex. Slit = 5 nm, Em. Slit = 5 nm). ([BrBP] = 0.5 mM, [CB[7]] = 0.5 mM, [CB[8]] = 0.25 mM).
