基本信息

项目摘要

With the support of the Inorganic, Bioinorganic and Organometallic Chemistry Program, Professor Ana de Bettencourt-Dias, of the Department of Chemistry at the University of Nevada Reno to study the efficiency of intersystem crossing of new ligands, which have a thiophene-carbazole-thiophene backbone, as a function of the conformation of the ligand and of the chelating group coordinated to the backbone. These ligands will be incorporated into lanthanide ion complexes and the stabilities and emission efficiencies of these complexes will be examined. The proposed ligands will serve as useful lanthanide ion sensitization probes and their respective complexes will be studied in terms of their photochemical and photophysical perperties. This project will show how the singlet and triplet states of the ligands depend on their chemical composition and conformation. The complexes will lead to new lanthanide-based emmitting materials with application in light-emitting diodes for flat panel displays. Undergraduate students involved in this project will gain research experience and learn several synthetic techniques in an area of chemistry that has practical applications in the field of color displays. Graduate students will acquire in-depth knowledge of coordination chemistry as well as the applications and research done in rare earth and materials chemistry. Finally, the above compounds may also be used as precursors for electroactive materials for hydrogen storage and spin valves, hole transport layers, catalysts and porous materials.
在无机、生物无机和有机化学项目的支持下,内华达州里诺大学化学系的Ana de Bettencourt-Dias教授研究了具有噻吩-咔唑-噻吩骨架的新配体的系统间交叉效率,该效率是配体构象和与骨架配位的螯合基团的函数。 这些配体将被纳入镧系离子配合物和这些配合物的稳定性和发光效率将被检查。 所提出的配体将作为有用的镧系离子敏化探针和它们各自的配合物将在其光化学和物理性质进行研究。这个项目将展示配体的单重态和三重态如何依赖于它们的化学组成和构象。 这些配合物将导致新的镧系元素基发光材料,并应用于平板显示器的发光二极管。 参与该项目的本科生将获得研究经验,并学习在彩色显示器领域具有实际应用的化学领域的几种合成技术。 研究生将深入了解配位化学以及在稀土和材料化学中的应用和研究。 最后,上述化合物还可以用作储氢和自旋阀的电活性材料、空穴传输层、催化剂和多孔材料的前体。
