摘要

开发新型有机红光材料对于制备高性能红光有机电致发光器件具有重要的研究意义。本文采用SUZUKI偶联反应，以芴酮为受体（A）、3，4，5-三甲氧基苯为给体（D）合成了新型D--A--D结构的有机红光材料（3MeFO）。通过,1,H NMR谱、,13,C NMR谱和X单晶衍射确认了分子结构，该化合物展示了较强的电荷转移作用和良好的共轭结构，其晶体的发射峰达到620 nm。从单晶结构中看出甲氧基的引入有利于在分子间形成大量的氢键，有效地增强了分子间的相互作用。同时，该材料表现出良好的热稳定性能和电化学性能，使得其在OLED中展示了良好的电致发光性能。

Abstract

To develop a novel red light luminescent material was important to prepare the high-efficiency organic light emitting devices. In this paper, a new kind of D--A--D red light luminogen utilizing fluorenone as acceptor and 3,4,5-trimethoxybenzene as donor was designed and synthesized, named 3MeFO. Its structure was confirmed by the,1,H NMR spectra,13,C NMR spectra and X-ray single crystal diffraction. The compound had strong charge transfer and -conjugated structure that contributed to the red shift and the PL peak of crystal was located at 620 nm. From the single crystal analysis, the introduction of methoxy groups had increased the intermolecular interaction owing to the formation of the hydrogen bond. Meanwhile, the compound exhibited excellent thermal stability properties, electrochemical performance that were benefit to prepare the OLED with the considerable electroluminescent properties.
