New analogs of the commercial dye Pyrromethene 567 (PM567), where the chromophore core is maintained but different substituents are introduced in position 8, have been synthesized, and their lasing properties when incorporated (dissolved or copolymerized) in polymeric matrices, using both linear and crosslinked polymers with different degrees of functionalization, have been studied. In general, the new materials exhibited laser emission with efficiencies and photostabilities much higher than those of the commercial dye PM567, demonstrating that by incorporating adequate chemical modifications in teh dipyrromethene.BF2 complexes, and selecting the appropriate polymeric formulations, efficient and photostable solid-state dye lasers competitive with their liquid counterparts can be developed.
