摘要：

The absorption and emission characteristics of several bis(dialkylamino)benzopyrylium dyes are compared, and their very different fluorescence quantum yields are correlated with the calculated energies of the lowest excited states of twisted cyanine dyes. The latter are models for selectively bridged compounds. The laser performance of the dyes is described and compared with well-known laser dyes. The 4-(2-carboxyphenyl)-substituted pyrylium salts are considerably more stable than the unsubstituted compounds.
