The fluorescence properties of the products formed by reaction of o-phthaldialdehyde with amino acids and their derivatives, in the presence of thiol compounds, have been studied. The emission spectra, quantum yields, and lifetimes depend on the primary amine and thiol compound used; the observations confirm the report (Simsons, S.S., Jr. and Johnson, D.F. (1978) J. Org. Chem 43, 2886--2891) that the product incorporates molecules of all three types of compounds. The fluorescence quantum yields… CONTINUE READING
