Abstract
Photochemistry of naphthalenic dyes. Naphthalenic dyes are used in the textile industry and as lasing molecules in dye lasers. In this work, we study their spectroscopic and photochemical properties. All these compounds are stable in the light (phi(d) congruent-to 10(-3)) but do not all have the same quantum yield of fluorescence (4 x 10(-2) < phi( f) < 1). This value depends on the nature of the substituent on the ar omatic ring. The mechanism of degradation involves the presence of rad icals and is dependent on the solvent.
