【摘要】 发光材料在照明和显示等领域应用广阔,寻求环境兼容、低成本和高效率的发光新材料意义深远。磷光锰(Ⅱ)配合物以其出色的发光效率、低成本和低毒性而备受关注。锰(Ⅱ)配合物的磷光发射产生于自旋禁阻的d-d跃迁,其发光特性主要取决于配体场的类型与强度。锰(Ⅱ)配位场对外界刺激相当敏感,易于发生变化,并直接影响其光物理性质,由此可实现发光颜色的可逆转换与调控。结合本课题组对磷光锰(Ⅱ)配合物的设计及其光致发光和电致发光性能的研究工作,本文综述了近年来卤化锰(Ⅱ)配合物发光材料和各种具有刺激响应发光变色效应的锰(Ⅱ)配合物及其在电致发光器件中的应用研究进展,并展望其发展前景及面临的挑战。更多还原

【Abstract】 Luminescent materials have been widely applied in the fields of lighting and display. It is significant to develop new luminescent materials with environmental compatibility, low cost and high efficiency.Phosphorescent manganese (Ⅱ) complexes have attracted much attention due to their excellent luminescent efficiency, low cost and low toxicity. The phosphorescence of manganese (Ⅱ) complexes originates from spin forbidden d-d transition and is mainly dependent on the type and strength of ligand field. Since the ligand field of manganese (Ⅱ) is sensitive to external stimuli and easy to change, which directly affects its photophysical properties, thus enabling the reversible conversion and regulation of luminous colors. Based on the research work in our group on the design of phosphorescent manganese (Ⅱ) complexes and their photoluminescence and electroluminescence properties, this article is aimed to review the recent progress of manganese (Ⅱ) halide complexes and various manganese(Ⅱ) complexes with stimulus-responsive luminescence and their applications in electroluminescent devices. The future development prospect and challenges in this field are prospected.更多还原
