中文摘要：

有机电致发光技术在通信、信息、显示和照明等领域显现出巨大的商业应用前景,十几年来一直是光电信息领域的研究热点之一。相对于无机电致发光材料,有机电致发光材料具有许多优点。芴作为一种具有刚性平面联苯结构的化合物,由于具有宽的能隙、高的发光效率和结构上易于修饰等特点,已成为一类受到各方关注的蓝光生色团。因此,芴类蓝光生色团在合成高效稳定电致蓝光材料、聚芴β相结构的调整、多功能化、主体材料、白光材料、有机激光及有机纳米发光材料等方面得到了广泛应用。本文从材料合成的角度综述了芴类蓝光生色团在合成有机电致发光材料方面所取得的最新研究进展,讨论了芴类蓝光生色团在上述领域应用过程中所存在的问题和功能拓展方向,并对下一步需要研究的热点做了展望。

英文摘要：

The organic electroluminescence（EL） technology,which has been the research focus in the field of electro-optical information,holds a wide range of potential application in domains of communication,information display and illumination and so on.Organic EL materials have many advantages when compared to their inorganic counterparts.Fluorene,as a kind of rigid plane biphenyl compound with wide band gap,high luminescent efficiency and high flexibility to modify the molecule skeleton,has been a key blue-emitting chromophore in organic EL.In this regard,fluorene-based blue-emitting materials are widely used in synthesis of highly efficient blue light-emitting materials,host materials,white light-emitting materials,organic lasers and organic nanomaterials,among which adjustment of the β phase structure and multiple functionalization are also main research directions.In this review paper,the applications of fluorene-based bule-emitting chromophores in organic EL are discussed in detail,and the progress of polyfluorene and its derivatives in the aspect of host materials and white materials is reviewed.Fluorene-based organic nanomaterials are concisely introduced.Thesynthesis methods of the polymers are concisely introduced.Finally,some issues to be addressed and hotspots to be further investigated are discussed.
