  • Boron dipyrromethenes with laser properties
    Patent number: 8796450
    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.
    Type: Grant
    Filed: October 4, 2013
    Date of Patent: August 5, 2014
    Assignee: Universidad de Guanajuato
    Inventors: Eduardo Peña Cabrera, Ismael Javier Arroyo Cordova, Fabiola Irene Lopez Vallejo
