35. 13C NMR spectra. The spiro carbon peak appeared at 67.0 ppm. According to the pH titration, compound 1 retained the spirocyclic form in the pH range of 4-14. Below pH 4, the fluorescence intensity increased, which implies that ring opening is occurring. Compound 1 is stable as a solid and a solution for several days.
