项目介绍



OLED器件是新一代照明及显示技术最有力的竞争者,而发光材料的分子设计、合成及相关性能的研究是该技术的核心,稀土配合物类OLED发光材料主要为中心离子发光,发光谱带窄、亮度高,这对高色纯的显示器件极其有利。稀土配合物既具有有机物高效率的优点,又具有无机物稳定性好的特点,是最有应用前景的一类发光材料。但目前该领域的研究主要集中于单核稀土配合物,而多元多核稀土配合物的发光性质非常优异,但具确定结构的多元稀土簇状配合物的电致发光性能与机理的研究相对较少。故本课题拟采用分子设计与自组装方法,构筑多元稀土簇状光电功能材料,研究其组成、结构、光电性质,系统探索稀土离子的种类、价态、配体的结构、取代基以及配合物的空间构型和分子间相互作用等因素对材料性能的影响。筛选具有高发光效率、发光强度的化合物,深入研究其发光性能、发光寿命、耐热性等。最终设计合成具有实际应用价值的多元稀土簇状光电功能材料。

OLED was thought to be the most powerful competitor among new generation lighting and display technology. Molecular design, synthesis and related properties of light-emitting materials are the key problems of the technology. Rare earth complexes of OLED light-emitting materials are mainly center ion luminescence. The narrow spectral bands and high brightness are favorable to good quality display device. Rare earth complexes not only have the advantages of high light-emitting efficiency of organic materials, but also have the good stability of inorganic materials. The complex is considered to be a kind of the most application prospect of luminescent materials. The present studies mainly focus on mononuclear rare-earth complexes, while the luminescence properties of multiple polynuclear rare-earth complexes are excellent. However, work on the resolved structure of multiple rare-earth clusters performance and mechanism of electroluminescence research is still rare. Herein, the molecular design and self-assembly method will be adopted to build multiple rare-earth clusters of photoelectric functional materials. Their composition, structure, optical, electrical properties will be studied. The factors affecting light-emitting material properties such as types of rare earth ions, valence state, ligand structure, the substituents and the complex spatial structure and molecular interactions will be systematically explored. The in-depth research of its electroluminescent properties, luminescence lifetime and heat resistance will be carried out. The compounds with the high luminous efficiency, luminous intensity will be selected. Finally, multiple rare-earth clusters of photoelectric functional materials with practical value will be obtained.
