摘要：

通过Sonogashira偶联等反应,合成了三嵌段化合物9,10-双-(对-(甲氧基二缩三乙二醇基)苯基乙炔基)蒽,通过¹H NMR和基质辅助激光解吸电离时间飞行质谱(MALDI-TOF-MS)对其结构进行了表征。利用差示扫描量热仪(DSC)、偏光显微镜(POM)及小角X射线散射仪(SAXS)等技术手段对其本体自组装行为进行了研究,结果表明,化合物在固态相自组装成近晶A相(SmA相)。光谱分析表明,该化合物继承了二取代蒽类发光材料具有高荧光量子产率(Φ_f)的特点,是一种性能良好的光致发光材料。

Abstract:

9,10-Bis((4-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)phenyl)ethynyl)anthracene(1) was synthesized by Sonogashira coupling. Its structure was characterized by ¹H NMR and MALDI-TOF mass spectroscopy. The self-assembling behavior of compound 1 was investigated by means of differential scanning calorimetry(DSC), thermal polarized optical microscopy(POM), and small-angle X-ray scattering(SAXS) at the bulk state. Compound 1 self-assembled into smectic A phase(SmA) in the solid state. Spectroscopic analysis suggested that compound 1 inherited the characteristic of high fluorescence quantum yield(Φ_f) of disubstituted anthracenes. The title compound 1 is a kind of photoluminescence materials with good performance.

Key words: self-assembly, anthracene, fluorescence quantum yield, smectic A phase, Sonogashira coupling reaction
