Sensitized decomposition of the trioxalatocobaltate(III) ion was studied in deoxygenated aqueous solution at room temperature, using biacetyl as an n-π<SUP>*</SUP> triplet sensitizer and 9-carboxyanthracene as a π-π<SUP>*</SUP> triplet sensitizer. In the presence of one of these sensitizers the photodecomposition rate of the complex was increased, and the plot of the reciprocal of the sensitization quantum yield as a function of the concentration of the complex gave a straight line for each sensitization system. On the other hand, the complex quenched the phosphorescence without affecting the fluorescence of the sensitizers, indicating a triplet energy transfer mechanism. A photokinetic treatment of the data for both the sensitized photolysis and the quenching process gave a result in line with proposed mechanism for bimolecular triplet energy transfer.
