Abstract
Abstract Electronic absorption and fluorescence spectra in different solvents have indicated that 2-hydroxycarbazole behaves as proton donor in both ground and electronically excited singlet states. In aqueous solutions, five prototropic species of 2-hydroxycarbazole have been detected and the prototropism has been established by the study of 2-methoxycarbazole. Acidity constants of the various acid—base equilibria have indicated that the behaviour of the molecule is similar in both ground and excited singlet states.
