    Circularly Polarized Luminescence by Visible-Light Absorption in a Chiral O-BODIPY Dye: Unprecedented Design of CPL Organic Molecules from Achiral Chromophores
    (Journal of the American Chemical Society, 2014) Márquez Sánchez-Carnerero, Esther María; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Rodríguez Agarrabeitia, Antonia; Ortíz García, María Josefa; Vo, Bryan G.; Muller, Gilles; Moya Cerero, Santiago de la
    Circularly polarized luminescence (CPL) in simple (small, nonaggregated, nonpolymeric) O-BODIPYs(R)-1 and (S)-1 by irradiation with visible light is first detected as proof of the ability of a new structural design to achieve CPL from inherently achiral monochromophore systems in simple organic molecules. The measured level of CPL (|glum|) in solution falls into the usual range of that obtained from other simple organic molecules (10−5−10−2range), but the latter having more complex architectures since axially chiral chromophores or multichromophore systems are usually required. The new design is based on chirally perturbing the acting achiral chromophore by orthogonally tethering a single axially chiral 1,1′-binaphtyl moiety to it. The latter does not participate as a chromophore in the light-absorption/emission phenom-enon. This simple design opens up new perspectives for the future development of new small-sized CPL organic dyes (e.g., those based on other highly luminescent achiral chromophores and/or chirally perturbing moieties), as well as for the improvement of the CPL properties of the organic molecules spanning their use in photonic applications.

    Unprecedented induced axial chirality in a molecular BODIPY dye: strongly bisignated electronic circular dichroism in the visible region
    (Chemical Communications, 2013) Márquez Sánchez-Carnerero, Esther María; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Rodríguez Agarrabeitia, Antonia; Bañuelos Prieto, Jorge; Arbeloa, Teresa; López Arbeloa, Íñigo María; Ortíz García, María Josefa; Moya Cerero, Santiago de la
    Enantiomeric bis(BODIPYs) 1a and 1b exhibit strong bisignated ECD due to the formation of a stable helical conformation with induced axial chirality, which allows efficient excito coupling of the BODIPY chromophores in the Vis region.

    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 La
    Boosted 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 cassettes

    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 La
    An 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.

    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 La
    Simple 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.

    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 La
    This 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.

    Del laboratorio al aula virtual en las prácticas de Química Orgánica
    (2021) Lora Maroto, Beatriz; Martínez Ruiz, María Paloma; Ortíz García, María Josefa; Osío Barcina, José de Jesús; Rodríguez Agarrabeitia, Antonia; Ray Leiva, César; Schad Alburquerque, Cristobal Martín
    Este proyecto surge de la necesidad de proporcionar a los estudiantes la posibilidad de adquirir las competencias asociadas a las prácticas de laboratorio de Química Orgánica, también en aquellas situaciones en las que no es posible la docencia presencial. Un claro ejemplo de ello ha sido el año 2020 con la situación del COVID-19 y el obligado confinamiento, que ha hecho imposible proporcionar a los estudiantes docencia práctica en el laboratorio. Pero esta no es la única situación en la que la posibilidad de recibir docencia práctica online se hace necesaria. Pueden existir casos de estudiantes que no puedan asistir presencialmente al laboratorio, por ejemplo, por motivos médicos, psicológicos, por discapacidad, cuando no se dispone de un laboratorio convenientemente adaptado, etc. La docencia online tiene la ventaja, frente a la docencia presencial, que se puede recibir desde cualquier lugar, de manera no necesariamente síncrona. Esto facilita que los estudiantes puedan organizar su docencia adaptada a su situación y necesidades. Así, en este proyecto se proporcionan las herramientas para posibilitar que todos los estudiantes puedan recibir esta docencia en cualquier situación, momento y lugar. Es evidente el reto que supone adaptar una docencia práctica de laboratorio a la docencia online, donde no es posible la manipulación de reactivos y material que se trabaja en un laboratorio de prácticas. Por ello, en este proyecto se han diseñado las actividades online que han de sustituir a la docencia presencial en el laboratorio, de manera que se logre la adquisición de las competencias asociadas a las prácticas por parte de la totalidad de los estudiantes, así como su correcta evaluación.
