中文摘要: 有机发光二极管(OLED)因其众多的性能优势而备受关注,但贵金属发光体的发光效率和成本等问题仍极大地制约其应用。Cu(I)配合物廉价易得、环境友好、发射特性好,是极有前景的替代材料。尤其是含卤素Cu(I)配位聚(簇)合物发光效率高,但目前的单源热蒸镀和溶液工艺却限制其用于OLED器件。本项目创新性地提出共沉积原位合成目标发光体同时成膜的制作方法,而目标非晶态膜层的形成,将通过我们创新设计的系列XAFS结构确证技术加以检测和确证。具体内容为:自主设计合成高效含卤素Cu(I)配位聚(簇)合物发光体,从中筛选出高效发光体作为目标结构进行共沉积原位合成镀膜,经过发光光谱等初步结构验证后,最终用XAFS方法确证目标非晶态镀层的分子结构。本项目的顺利开展将有助于建立共沉积镀膜的创新制作工艺,阐明共沉积镀膜的内在规律,打通新型发光材料到OLED器件的制作通道,为OLED的发光效率和成本改善提供基础支撑。

英文摘要: Organic Light-Emitting Diodes (OLEDs)are attracting great attention due to their numerous property predominance. However, the problems of luminescent efficiency and cost limit the application. Cu(I) coordinated compounds, which are cheap, environmentally friendly and good emitter, are the prosperous candidates. Cu(I) coordinated clusters or polymers containing halogens especially show high efficiency of luminescence. Nevertheless, the single heat-source evaporation method and solution technique restrict the application on OLED devices. This project innovatively proposes a new way to fabricate the goal luminophor in situ by the codeposition technique with the formation of the films in the meantime. The formation of the noncrystalline film will be tested and confirmed by our innovatively designed series of XAFS structural confirmation technique. The research will be carried out as follow. The Cu(I) coordinated clusters or polymers containing halogens with high luminescent efficiency will be designed and synthesized initiatively. The selected luminophors with high efficiency will be set as the goal structures to fabricate in situ by the codeposition technique for coating films. After the primitive structural check through luminescent spectra etc., the molecular structure of the noncrystalline film will be confirme
