中文摘要：
降低器件制备成本和提高器件工作寿命是有机电致发光器件（OLED）产业化发展所面临的两大难题。溶液方法制备有机小分子OLED器件由于其成本低、工艺简单、性能优越，受到人们的广泛关注，但器件的稳定性较差，距实用化仍有一定的距离。因此，针对溶液方法制备的有机小分子OLED器件的老化机理和稳定性问题开展研究具有重要意义。本项目通过研究溶液方法制备的有机小分子薄膜性能影响OLED器件老化的关键因素，以及器件的电学老化、黑点老化和光/热老化的成因，构建器件老化物理模型，揭示器件的老化机理。以此为指导，通过有针对性地调控发光层、主体材料和器件结构来改善器件的稳定性。通过本项目的实施，初步建立溶液方法制备有机小分子OLED器件的老化机理与提高这类器件稳定性的实践方法，为溶液方法制备的有机小分子OLED器件及其它有机半导体器件的稳定性研究奠定重要的理论和实践基础，为促进OLED器件产业化发展做出一定贡献。
