Abstract
A family of three 8-alkyl boron dipyrromethenes 1, 2, and 3 has been prepared. These compounds are characterized by emission in the green region of the electromagnetic radiation spectrum and exhibit an almost double laser efficiency than other commercial dyes and much greater photostability. The 8-alkyl boron dipyrromethenes are prepared by catalytic hydrogenation (reduction) of the corresponding 8-alkenyl boron dipyrromethenes, which are obtained by Liebeskind-Srogl coupling of thiomethylboron dipyrromethene with an alkenyl boronic acid.
