Photophysical Properties of Some Quindoline Bases and their Salts

Abstract

The title compounds are used as sensitizers in electrophotography. The dependence of their absorption and luminescence characteristics on the substituent, medium and temperature is investi gated. The influence of various factors on the equilibrium base -salt in solution is elucidated. On the basis of changes in the absorption spectra with concentration the equilibrium constants Kq are determined.
