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.

有了这个奖项，化学合成计划正在资助内华达大学里诺分校的Ana de Bettencourt-Dias教授合成和研究新衍生的吡啶-双（恶唑啉）（Pybox）镧系元素络合物的电子物理学。 虽然Pybox配体已广泛用于过渡金属催化的有机合成，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配体与镧系离子发光敏化的结构-功能关系。 此外，水溶性复合物正被用于生物发光，因为是复合物，可以纳入聚合物，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更广泛的影响。此外，镧系元素离子化学的研究可能与锕系元素的化学有关，因为镧系元素络合物有时被用作替代物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训本科生、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。
