Steady-state and time-resolved fluorescence techniques were employed to study the excited-state proton transfer (ESPT) from a reversibly dissociating photoacid, 2-naphthol-6,8-disulfonate (2N68DS). The reaction was carried out in water and in acetoni

Steady-state and time-resolved fluorescence techniques were employed to study a superphotoacid with a pKa* of ∼−7, the chlorobenzoate phenol cyanine picolinium salt (CBCyP) in acetonitrile–water mixtures. We found that the time-resolved fluores

Steady-state and time-resolved fluorescence techniques were employed to study the excited-state proton transfer (ESPT) rate to methanol, ethanol and propanol of a new photoacid, the chloro benzoate phenol cyanine picolinium salt (CBCyP). We found tha

We employed steady-state and time-resolved fluorescence techniques to study the rates of excited-state proton and deuteron transfer (ESPT) from an irreversible photoacid - 1-naphthol-4-sulfonate - to solvent mixtures of H2O and D2O. We found that the

Steady-state and time-resolved fluorescence techniques were employed to study the photoacidity of a newly synthesized photoacid, the chloro benzoate cyanine picolinium salt. It was found that the ESPT rate constant is ultrafast in water ( k PT = 6.2

We used the time-resolved fluorescence technique to measure the excited-state proton-transfer (ESPT) rates from 8-hydroxy-1,3,6-pyrenetrisulfonate (HPTS) to solvent mixtures of H2O and D2O. We found an anomalous deviation from linear mole-fraction be

We used the photoacid 8-hydroxy-1,3,6-pyrenetrisulfonate (HPTS) that converts blue photons to acidic protons in water, with an efficiency of close to 100%, and determined that this treatment conferred changes to colony morphology of the plant pathoge

Steady-state and time-resolved fluorescence techniques were employed to study the excited-state proton transfer (ESPT) to water and D2O of a new photoacid, phenol benzoate cyanine picolinium salt (BCyP). We found that the ground-state pKa is about 6.
