Pyridine-bis(oxazoline) derivatives for enhanced Ln(III) emission in aqueous systems and in the solid state

利用该奖项，化学合成项目资助内华达大学里诺分校的Ana de Bettencourt-Dias教授合成和研究新型衍生吡啶-双（恶唑啉）（Pybox）镧系配合物的光物理学。虽然Pybox配体已广泛应用于过渡金属催化的有机合成中，但直到最近才报道了它们有效敏化镧系离子发光的能力。特别是，该项目旨在建立Pybox配体的结构-功能关系，与镧系离子发光的敏化有关。此外，水溶性配合物正成为生物发光的目标，就像可以结合到聚合物中的配合物一样，用于固态照明应用。如上所述，该项目在生物成像和固态材料领域具有潜在的长期科学影响。此外，镧系离子化学的研究与锕系元素的化学有潜在的联系，因为镧系元素配合物有时被用作替代品来模拟放射性锕系元素的化学。更广泛的教育影响包括在多学科环境中培养本科生，研究生和博士后同事，包括合成有机金属化学和吸收，激发和发射光谱学的要素。

With this award, the Chemical Synthesis Program is funding Professor Ana de Bettencourt-Dias at the University of Nevada-Reno to synthesize and study the photophysics of new derivatized pyridine-bis(oxazoline) (Pybox) lanthanide complexes. While Pybox ligands have been extensively used in transition-metal catalyzed organic synthesis, it was only recently that their ability to efficiently sensitize lanthanide ion luminescence was reported. In particular, the project seeks to establish a structure-function relationship of Pybox ligands with respect to sensitization of lanthanide ion luminescence. Moreover, water-soluble complexes are being targeted for use in bioluminescence, as are complexes that can be incorporated into polymers, for solid state lighting applications.As noted above, this project has potential long-term scientific broader impacts in the areas of bioimaging and solid state materials. Moreover, research in lanthanide ion chemistry is potentially connected with the chemistry of actinides, as lanthanide complexes are sometimes used as surrogates to mimic the chemistry of the radioactive actinides. Educational broader impacts include the training of undergraduate, graduate and postdoctoral co-workers in a multidisciplinary environment, including elements of synthetic organometallic chemistry and ofabsorption, excitation and emission spectroscopy.
