Competitive inhibition of a metal-free porphyrin oxygen-reduction catalyst by water.

A stopped-flow method is used to study the effects of water and reactant acid anion TB(-) = tetrakis(pentafluorophenyl)borate on the homogeneous oxygen reduction catalyzed by the protonated tetraphenylporphyrin. Observed competitive inhibition of the catalyst is linked to the DFT free energy of extraction of O(2), water, and TB(-) from the porphyrin complex.
