Item Spiranic BODIPYs: a ground-breaking design to improve the energy transfer in molecular cassettes(Chemical Communications, 2014) Márquez Sánchez-Carnerero, Esther María; Gartzia-Rivero, Leire; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Rodríguez Agarrabeitia, Antonia; Ortiz García, María Josefa; Bañuelos Prieto, Jorge; López Arbeloa, Íñigo María; Moya Cerero, Santiago De LaBoosted excitation energy transfer in spiranic O BODIPY/polyarenecassettes, when compared with the parent non-spiranic (flexible) system, is highlighted as a proof for the ability of a new structural design to improve the energy transfer in molecular cassettesItem Preparation of dipyrrins from F-BODIPYs by treatment with methanesulfonic acids(RSC Advances, 2015) Urieta Mora, Javier; Lora Maroto, Beatriz; Moreno Jiménez, Florencio; Rodríguez Agarrabeitia, Antonia; Ortiz García, María Josefa; Moya Cerero, Santiago De LaAn alternative metal-free soft procedure for the preparation of dipyrrins from F-BODIPYs is reported. The new method makes possible to obtain certain dipyrrin derivatives that were unaccessible from F-BODIPYs to date. To demonstrate the ability of the new procedure, dipyrrins having highly reactive groups, such as chloro, cyano or acetoxyl, have been easily obtained from the corresponding F-BODIPY, which shows the synthetic utility of the reported methodology.Item Bis(haloBODIPYs) with Labile Helicity: Valuable Simple Organic Molecules That Enable Circularly Polarized Luminescence(Chemistry: a european journal, 2016) Ray Leiva, César; Márquez Sánchez-Carnerero, Esther María; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Rodríguez Agarrabeitia, Antonia; Ortiz García, María Josefa; López Arbeloa, Íñigo María; Bañuelos Prieto, Jorge; Cohovi, Komlan D.; Lunkley, jamie L.; Muller, Gilles; Moya Cerero, Santiago De LaSimple organic molecules (SOM) based on bis(haloBODIPY) are shown to enable circularly polarized luminescence (CPL), giving rise to a new structural design for technologically valuable CPL-SOMs. The established design comprises together synthetic accessibility, labile helicity, possibility of reversing the handedness of the circularly polarized emission, and reactive functional groups, making it unique and attractive as advantageous platform for the development of smart CPL-SOMs.Item Circularly Polarized Luminescence from Simple Organic Molecules(Chemistry: a european journal, 2015) Márquez Sánchez-Carnerero, Esther María; Rodríguez Agarrabeitia, Antonia; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Muller, Gilles; Ortiz García, María Josefa; Moya Cerero, Santiago De LaThis article aims to show the identity of “circularly polarized luminescent active simple organic molecules” as a new concept in organic chemistry due to the potential interest of these molecules, as availed by the exponentially growing number of research articles related to them. In particular, it describes and highlights the interest and difficulty in developing chiral simple (small and non-aggregated) organic molecules able to emit left- or right-circularly polarized light efficiently, the efforts realized up to now to reach this challenging objective, and the most significant milestones achieved to date. General guidelines for the preparation of these interesting molecules are also presented.Item Polar ammoniostyryls easily converting a clickable Q1 lipophilic BODIPY in an advanced plasma membrane probe†(Journal of Materials Chemistry B, 2023) Serrano-Buitrago, Sergio; Muñoz Úbeda, Mónica; Almendro Vedia, Víctor Galileo; Sánchez-Camacho, Juan; Lora Maroto, Beatriz; Moreno, Florencio; Bañuelos, Jorge; García-Moreno, Inmaculada; López Montero, Iván; Moya Cerero, Santiago De La; Moreno Jiménez, FlorencioA very simple, small and symmetric, but highly bright, photostable and functionalizable molecular probe for plasma membrane (PM) has been developed from an accessible, lipophilic and clickable organic dye based on BODIPY. To this aim, two lateral polar ammoniostyryl groups were easily linked to increase the amphiphilicity of the probe and thus its lipid membrane partitioning. Compared to the BODIPY precursor, the transversal diffusion across lipid bilayers of the ammoniostyryled BODIPY probe was highly reduced, as evidenced by fluorescence confocal microscopy on model membranes built up as giant unilamellar vesicles (GUVs). Moreover, the ammoniostyryl groups endow the new BODIPY probe with the ability to optically work (excitation and emission) in the bioimaging-useful red region, as shown by staining of the plasma membrane of living mouse embryonic fibroblasts (MEFs). Upon incubation, this fluorescent probe rapidly entered the cell through the endosomal pathway. By blocking the endocytic trafficking at 4 °C, the probe was confined within the PM of MEFs. Our experiments show the developed ammoniostyrylated BODIPY as a suitable PM fluorescent probe, and confirm the synthetic approach for advancing PM probes, imaging and science.Item Dissimilar-at-boron N-BODIPYs: from light-harvesting multichromophoric arrays to CPL-bright chiral-at-boron BODIPYs(Organic Chemistry Frontiers, 2023) Ray, César; Avellanal-Zaballa, Edurne; Muñoz Úbeda, Mónica; Colligan, Jessica; Moreno Jiménez, Florencio; Muller, Gilles ; López Montero, Iván; Bañuelos, Jorge; Lora Maroto, Beatriz; Moya Cerero, Santiago De LaWe report a workable and easy approach for the direct post-multifunctionalization of common BODIPYs (F-BODIPYs) with minimal interference to the starting photophysical behavior. It entails the easy transformation of an F-BODIPY into the corresponding N-BODIPY by using a dissimilarly-N,N′-disubstituted bis(sulfonamide), which is easily obtained from ethane-1,2-diamine. This approach is exemplified by the rapid synthesis of a selected battery of unprecedented dissimilar-at-boron N-BODIPYs, which are rationally designed to act as efficient multichromophoric arrays for light harvesting by excitation energy transfer, as specific bioprobes for fluorescent imaging, or as efficient chiroptical dyes exhibiting visible circular dichroism and circularly polarized luminescence. Noticeably, this approach has led to the synthesis of the first CPL-bright chiral-at-boron BODIPYs, a significant novelty in BODIPY chemistry and CPL emitters
