Abstract

Polymethylmethacrylate (PMMA) is a convenient solvent for studies of the fluorescence, phosphorescence, and triplet-triplet absorption of a number of aromatic hydrocarbons and N-heterocyclic compounds. Theoretical assignments of some triplet states are discussed briefly. Triplet lifetimes of the solutes have been determined at 77 and 293 K by phosphorescence decay measurements and by kinetic spectrophotometry. Non-exponential decays of compounds with triplet lifetimes less than 0.1 s at 293 K have been attributed to diffusion-controlled quenching reactions occurring in low viscosity regions in the polymer.
