Rational molecular design enhancing the photonic performance of red-emitting perylene bisimide dyes Avellanal Zaballa, Edurne Durán Sampedro, Gonzalo Prieto Castañeda, Alejandro Rodríguez Agarrabeitia, Antonia García Moreno, Inmaculada López Arbeloa, Íñigo María Bañuelos Prieto, Jorge Ortiz García, María Josefa 547.1 539.19 535.374 Molecular design Multichromophoric organic aechitectures BODIPY Perylene red Light harvesters Red-emitting lasers Molecular antennas Optica (Química) Química orgánica (Química) Láseres 2306 Química Orgánica 2209.10 Láseres We report the synthesis of novel multichromophoric organic architectures, where perylene red is decorated with BODIPY and/or hydroxycoumarin dyes acting as light harvesters and energy donors. The computationally-aided photophysical study of these molecular assemblies reveals a broadband absorption which, regardless of the excitation wavelength, leads solely to a bright red-edge emission from perylene bisimide after efficient intramolecular energy transfer hops. The increase of the absorbance of these molecular antennas at key pumping wavelengths enhances the laser action of the commercial perylene red. The herein applied strategy based on energy transfer dye lasers should boost the use of perylene-based dyes as active media for red-emitting lasers.
