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。
Organic electroluminescence technology has shown great commercial application prospects in the fields of communications, information, display and lighting, and has been one of the hot spots in the field of optoelectronic information for more than ten years. Organic electroluminescent materials have many advantages over inorganic electroluminescent materials. As a kind of compound with rigid planar biphenyl structure, fluorene has become a kind of blue chromophore with all kinds of concerns due to its wide energy gap, high luminous efficiency and structurally easy modification. Therefore, the fluorene blue chromophore has been widely used in the synthesis of highly efficient and stable blue electroluminescent materials, the adjustment of β-phase structure of polyfluorene, multifunctionalization, host materials, white light materials, organic lasers and organic nano luminescent materials. In this paper, we review the latest research progress of fluorene blue chromophores in the synthesis of organic electroluminescent materials from the perspective of material synthesis, and discuss the problems and functions of fluorene blue chromophores in the application of these fields Direction, and the next step needs to be studied hot prospects.
