應用

8-Ethoxy-N,N,N′,N′,N″,N″-hexamethylpyrene-1,3,6-trisulfonamide is an analog of 8-hydroxy-N,N,N′,N′,N″,N″-hexamethylpyrene-1,3,6-trisulfonamide (HPTA), a photoacid, used to investigate the steps involved in excited-state deprotonation in polar solvents using pump-probe spectroscopy and time correlated single photon counting fluorescence spectroscopy.
