Abstract
Due to their very substantial fluorescence emission, pyrylium and thio pyrylium salts are widely used as laser dyes and photosensitizers. Thi s paper deals with the fluorescence properties (quantum yields and wav elengths of the fluorescence maxima as well as the Lifetimes of the si nglet excited states) of eight pyrylium and ten thiopyrylium salts, wi th special emphasis on the effect of alpha and gamma substitutions of the heterocycle.
