The mechanism of photochemical reactions of pyrenetetrasulfonate (PyTS) in aqueous solution was studied using laser flash photolysis-transient absorption spectrum techniques under irradiation at 355 nm. The characteristic absorption peaks of the excited singlet (PyTS^1*) at 260 nm, the excited triplet (PyTS^3*) at 300 nm, and the anion radical (PyTS^-·) at 330 nm were first confirmed. Self-quenching and reaction with PyTS were regarded as the main decay channels for hydrated electrons (e_aq^-), and the pseudo-first-order rate constant of hydrated electrons with PyTS was determined to be 2.7× 10⁵ s^-1. The quantum yield of e_aq^- generated via two-photon ionization of PyTS was computed to be 3.2×10^-2 under these conditions.
