Abstract Quenching rate constants,k q, of the uranyl excited state by phenolic compounds were determined in H3PO4 1M by luminiscence techniques. A plot of logk q vs. ΔG2 for the photo-induced electron transfer reaction rendered a slope value of 4.0 eV−1 which was much smaller than that predicted from the Rehm-Weller correlation (16.9 eV−1). This value is similar to those found for aromatic quenchers that fail to interact with the UO2 2+ ground state, and quench the uranyl luminescence through a non-radiative donor-acceptor complex formation.
