Physical Chemistry Chemical Physics, vol. 19, n.o 20, mayo de 2017, pp. 13210-18. pubs.rsc.org, https://doi.org/10.1039/C7CP01626C.1463-907610.1039/C7CP01626Chttps://hdl.handle.net/20.500.14352/18148We 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.engjournal articlehttp://dx.doi.org/10.1039/c7cp01626chttp://pubs.rsc.org/en/content/articlelanding/2017/cp/c7cp01626c#!divAbstractrestricted access547.1539.19535.374Molecular designMultichromophoric organic aechitecturesBODIPYPerylene redLight harvestersRed-emitting lasersMolecular antennasOptica (Química)Química orgánica (Química)Láseres2306 Química Orgánica2209.10 Láseres
