(a) Fluorescence spectra of 10 µM compound 1 upon addition of different concentration of HSA (0 10 µM). Insert: Plot of the fluorescence enhancement (F/F0 − 1) at 508 nm to HSA concentrations. (b) Fluorescence spectra of 10 µM compound 2 upon addition of different concentration of HSA (0–10 µM). Insert: Plot of the fluorescence enhancement (F/F0 − 1) at 517 nm to HSA concentrations. All experiments were performed in1 mM HEPES buffer containing 1% DMSO, pH = 7.4.F: The fluorescence intensity of dye in the presence of HSA. F0: The fluorescence intensity of dye in the absence of HSA.
