    Rational molecular design enhancing the photonic performance of red-emitting perylene bisimide dyes
    (Physical Chemistry Chemical Physics, 2017) 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
    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.

    Exploring the Application of the Negishi Reaction of HaloBODIPYs: Generality, Regioselectivity, and Synthetic Utility in the Development of BODIPY Laser Dyes
    (Journal of Organic Chemistry, 2016) Palao Utiel, Eduardo; Durán Sampedro, Gonzalo; Moya Cerero, Santiago De La; Madrid, Miriam; García López, Carmen; Rodríguez Agarrabeitia, Antonia; Verbelen, Bram; Dehaen, Wim; Boens, Nöel; Ortiz García, María Josefa
    The generality of the palladium-catalyzed C–C coupling Negishi reaction when applied to haloBODIPYs is demonstrated on the basis of selected starting BODIPYs, including polyhalogenated and/or asymmetrical systems, and organozinc reagents. This reaction is an interesting synthetic tool in BODIPY chemistry, mainly because it allows a valuable regioselective postfunctionalization of BODIPY chromophores with different functional groups. In this way, functional patterns that are difficult to obtain by other procedures (e.g., asymmetrically functionalized BODIPYs involving halogenated positions) can now be made. The regioselectivity is achieved by controlling the reaction conditions and is based on almost-general reactivity preferences, and the nature of the involved halogens and their positions. This ability is exemplified by the preparation of a series of new BODIPY dyes with unprecedented substitution patterns allowing noticeable lasing properties.
