Synthesis of Organic Electroluminescent Material Fluorene Derivatives

芴衍生物被认为是很有开发前景和实用价值的一类发光材料,它具有较为优异的综合性能,如良好的发光效率,较好的热稳定性等。本研究工作采用条件温和、产率较高的合成路线,对芴为单体进行官能团修饰,制备了9,9-二甲基芴、9,9-二甲基-2-硝基芴、9,9-二甲基-2-氨基芴、N-(4-联苯基)-9,9-二甲基-2-氨基芴。并对影响反应的重要因素进行了考察和讨论。

The fluorene derivatives are described as a kind of luminescent material with good development perspective and practical value.The fluorene derivatives possess outstanding comprehensive properties,such as good luminous efficiency and better thermal stability,etc.The synthesis route with the characteristic of moderate reaction conditions and high yield is adopted for the functional group modification of fluorine.The 9,9-dimethylfluorene,9,9-dimethyl-2-nitrofluorene,9,9-dimethyl-9H-fluoren-2-amine and N-（biphenyl-4-yl）-9,9-dimethyl-9H-fluoren-2-amine are prepared,and the major factors influencing the reaction are investigated and discussed.
