Quenching of Triplet State Benzophenone by Metal(II) 1,3-Diketonates in Solution

Abstract Steady-state phosphorescence measurements have been carried out for the quenching of benzophenone triplet state by several transition metal β-diketonate complexes. The results suggest a complex quenching mechanism in which energy and electron transfer processes might be involved. Key Words: phosphorescencebenzophenonequenchingmetal β-diketonates
