The Influence of Sodium Polyvinylsulfate on the Photodimerization of Acridizinium PerchlorateDuring the irradiation of aqueous solutions of acridizinium perchlorate (λexc = 405 nm) a photodimer of this compound is formed. The quantum yield of the reaction depends on the concentration of the acridizinium ion. In 10-4 m solutions the quantum yield of dimerization is π = 0.0054 ± 0.0005. Addition of the anionic polyelectrolyte sodium polyvinylsulfate leads to a considerable increase of the quantum yield (up to π = 0.6) in dependence on the concentration of the polyion. A kinetic model is developed, including the electrostatic interaction of the acridizinium cation and the polyanion.The influence of diazonium cations as competitive agent is investigated and dicussed.
