Fluorescence characterizations of TPE-Q4 and TPE-Q4 DSP5. (a) Fluorescence spectra of TPE-Q4 (1 μM) in water with different concentrations of DSP5 (inset images: (A) DSP5; (B) TPE-Q4 DSP5; (C) TPE-Q4 in water); (b) fluorescence spectra of TPE-Q4 DSP5 in PBS of different pH values. Experimental conditions: = 330 nm; = 475 nm; slit widths: Ex. 5 nm, Em. 5 nm; 298 K; [TPE-Q4] = 1 μM, [DSP5] = 4 μM. (c) Fluorescence decay profiles and (d) absolute fluorescence quantum yields of TPE-Q4 and TPE-Q4 DSP5. Experimental conditions: = 365 nm, 298 K, [TPE-Q4] = 1 μM, [DSP5] = 4 μM in water.
