Photoreactivity of 1-Pyrenylmethyl Esters. Dependence on the Structure of the Carboxylic Acid Moieties and the Nature of the Excited States

Article abstract of DOI:10.1246/cl.1987.1729

While the photolysis of 1-pyrenylmethyl phenylacetates in methanol gave the original phenylacetic acids, irradation of the 1-naphthoate and 9-anthracenecarboxylate leads to the formation of the intramolecular exciplexes that are inert to the photolysis.The Φ_f and τ_f values of these esters have been determined.
