Synthesis, Photophysical Properties, and Laser Behavior of 3-Amino and 3-Acetamido BODIPY Dyes

摘要

The asymmetrically substituted BODIPY dyes 9a and 9b have been synthesized through a key redox step involving the r-nitroso derivativeudof the starting pyrrol. Both dyes emit fluorescence with quantum yields of ca. 0.7, but only 8b behaves as a good laser dye, with an efficiencyudof 48% in ethanol solution.
