Long-lived triplet excitons are generated by laser excitation of a zinc porphyrin Langmuir-Blodgett film. The transient T-T spectrum is similar to that obtained in the liquid phase and the triplet excitons disappear with second-order kinetics by T-T annihilation. Their half-life varies from 1 lo? 10
