Abstract
The excited-state intramolecular proton transfer of 2-(o-hydroxyaryl)benzaz oles has been studied by emission spectroscopy. Although both 2-(2-hydroxy- 3-aryl)benzazole and 2-(1-hydroxy-2-aryl)benzazole consist of an aryl moiet y, a benzazol-2-yl group and an OH group, their emission properties are ver y different fur the reasons that can be explained in terms of our previousl y offered nodal-plane model.
