The 3 most common classes of photoacids, R*NH2, R*NH3+ and R*OH are compared. Clearly the molecular origins of photoacidity need to be considered not as a general phenomenon but separately for each class of photoacids.

Deciphering Photoacidity by Following Electronic Charge Distribution Changes along the Photoacid Förster Cycle with Time-Resolved Nitrogen K-Edge X-Ray Absorption Spectroscopy

Publikováno v: The 22nd International Conference on Ultrafast Phenomena 2020.

We locally probe with picosecond N K-edge spectroscopy electronic structure changes along all stages of the Förster photocycle of a prototypical photoacid, and determine how photoacid behaviour is driven by the conjugate photobase side.

Proceedings of the National Academy of Sciences of the United States of America, National Academy of Sciences, 2019, 116 (42), pp.20837-20843. ⟨10.1073/pnas.1909498116⟩

Carbonic acid H(2)CO(3) (CA) is a key constituent of the universal CA/bicarbonate/CO(2) buffer maintaining the pH of both blood and the oceans. Here we demonstrate the ability of intact CA to quantitatively protonate bases with biologically-relevant
