9,10-双-三甲基硅乙炔基蒽的合成及其光谱性质研究

Synthesis and spectral properties of 9,10-bis(2-(trimethylsilyl) ethynyl) anthracene

苯乙炔类化合物是一类π-共轭化合物,具有重要的理论研究价值,在分子导线、分子传感器、液晶显示中的偏振器、发光二极管和能量传输材料等光电领域有着广泛的应用。目前对苯乙炔类聚合物和齐聚物的研究很多,而对苯乙炔类小分子研究得很少。

9,10-Bis（trimethylsilylethynyl） anthracene was prepared by a coupling reaction of dibromoanthracene dibromobenzene and trimethylsilylethyne,using PdCl2（PPh3） 2 and CuI as catalysts.A mixed solvent of THF/diethylamide was used as the media of the coupling reaction.The product was obtained with desired yields and it was characterized by IR,UV,1HNMR.Furthermore,the UV fluorescence spectral properties of the product and the interaction between bromobenzene and nitrobenzene were studied.
