9,9-二丁基-2-(N-9-菲基)胺基芴的合成与性能研究

Synthesis and Properties of N-( 9,9-dibutyl-9H-fluoren-2-yl)Phenanthren-9-amine

以芴为基础原料,经NBS溴化,然后与溴代正丁烷反应生成9,9-二甲基-2-溴芴,最后与9-胺基菲通过Buchwald-Hartwig偶联反应合成了新型的空穴传输材料中间体9,9-二丁基-2-(N-9-菲基)胺基芴,并通过核磁共振、高分辨质谱和元素分析等方法对产物进行了表征,此外还利用UV-Vis光谱和TGA对其光学性质和热力学稳定性进行了研究。该化合物在紫外可见光区338 nm处呈现强的吸收带,热力学分解温度在320℃左右,表明此化合物在有机光电领域具有良好的应用前景。

N - （ 9,9 - dibutyl - 9H - fluoren - 2 - yl ） phenanthren - 9 - amine as new hole - transport material was synthesized by NBS bromination and Buchwald-Hartwig coupling reaction, and it was fully characterized by 1H NMR, 13C NMR, HRMS and elemental analysis. The optical and thermal properties were also determined with TGA and UV-Vis spectrum. This compound displayed an intense band in the UV/Vis region centered at 358 nm and had a decomposition temperature above 320℃, illustrating the 13otential for opto-electronic applications.
