Diseño y caracterización de compuestos organoboro fluorescentes y sus aplicaciones funcionales

Resum

The present Doctoral Thesis entitled as “Design and Characterization of Fluorescent Organoboron Dyes and their Functional Applications” is focused on the design, photophysical characterization and application of fluorescent molecules containing boron as the main element. Exactly, this Memory will include organoboron compounds such as boronic acids like building blocks, arylboranes with chelates ligands (N,C; N,N; N,O), etc. An organoboron dye essentially contains at least one atom of B in its structure and, as well, posess at least an alkyl group and another two or three substituents that may contain halides, hydroxyl or alkoxy groups. Along the history, organoboron compounds have been widely used due to its interesting photophysical properties. In recent years, the growing interest in these compounds is because among them, in how efficient they are at transporting electrons and their many applications as luminescent polymeric materials, chromophores model for the study of the transfer of electrons and chemical sensors. The Thesis consists of a general introduction that will incorporate a review about the organic dyes, including its main features, photophysical properties and more relevant application of these components. Likewise, it describes proceedings and photophysics phenomena that will be mentioned along the different following chapters. After this introduction it is exposed the objectives that have been acquired during the realization of this Doctoral Thesis. Afterwards, this Memory is divided in four chapters, three of them have been derived in articles already published about every outcome in each project, and a fourth chapter that is being finished in another articles. Finally, the last chapter summarizes and concludes all the work that has been developed during the Doctoral Thesis. All the projects developed here have a character notably multidisciplinary and it would have not been possible without the collaboration of other investigation groups, nationals (Universidad de Sevilla - Instituto de Investigaciones Químicas y el Consejo Superior de Investigaciones Científicas y, Universidad de Málaga - BIONAND) and internationals (Universidad de Brescia, Lisboa).
