摘　　要：以1,4-二羟基蒽醌和苯胺为原料通过双芳胺化和氟硼络合得到了7个化合物,产率最高达到69.2%.对荧光性能进行检测,化合物在溶液中具有红色荧光但是没有展现固体荧光,斯托克斯位移达到64~86nm.吸电子基团使荧光明显增强,推电子基团使荧光减弱,其中强推电子基团-OCH_3使荧光几乎发生淬灭,同时重原子效应明显影响荧光强度使其减弱;最后研究了浓度对荧光性能的影响,发现浓度达到3×10^(-5) mol/L时,荧光强度增加到最强,达到4×10^(-4) mol/L时,几乎接近淬灭.1,4-dihydroxyanthraquinone and aniline were used as raw materials to obtain seven compounds by double amination and fluoroboron complexation,the highest yield was 69.2%.The detection of fluorescence properties revealed that the compounds exhibited red fluorescence in the solution state but did not show fluorescence in solid state,they showed large Stokes shift were 64-86 nm.The fluorescence intensity is enhanced largely by introducing the electronwithdrawing groups,and it is weakened by introducing the electron-donating groups into the compounds.It is worth noting that strong electron-donating group（-OCH3） made the fluorescence almost quenched,and the effect of heavy atoms affected the fluorescence intensity significantly,it made the fluorescence intensity weakened.Finally,the effect of concentration on the fluorescence properties was investigated.When the concentration was 3×10^-5 mol/L,the fluorescence intensity increased to the maximum,when the concentration reached 4×10^-4 mol/L,which shows a almost complete quenching.
