摘要：

Just as litmus paper changes from red to blue with an increase in pH, so the fluorescence emission of the oxazole derivative 1 shifts from green to blue. Ratiometric measurements of the fluorescence emissions of the two species, after one- or two-photon excitation, allow 1 to be employed as a pH sensor over the mid-pH range.
