Figure 1.
Fluorescence response of 5 μM compound 1 to 100 μM H2O2 after 30 min. The black and red lines were recorded before and after H2O2 addition, respectively (top). Spectra were acquired in 0.1M phosphate buffer, pH 7.4 (λex = 332 nm). The bottom panel shows the color change before (left) and after hydrogen peroxide addition (right).
