Abstract

It has recently been suggested that the fluorescence of 3-aminophthalate in aqueous or dimethylsulfoxide (DMSO) solution can be described by a four level scheme1. The ground state species upon excitation undergoes considerable hydrogen bonding re-arrangements and in DMSO even complete intramolecular proton transfer occurs. In order to explain the differences in spectral and quantum yield behavior between the fluorescence of 3-aminophthalate and the chemiluminescence of luminol 1–4, we have suggested that the chemiluminescence process populates the lower of the two excited levels primarily1.
