以9,10-菲醌为原料经Buchwald-Hartwig偶联反应得到两个有机分子M1和M2.它们的结构经质谱和核磁氢谱得到验证.在紫外光激发下,M1的最大发射波长为447 nm,呈现蓝色荧光,可用做蓝色有机发光材料;M2在可见光范围无明显荧光,因为羰基吸电子基团使得π-π*跃迁为禁阻跃迁,导致荧光猝灭.%Two organic molecules M1 and M2 were synthesized with 9,10-Phenanthrenequinone as the raw material by Buchwald-Har-twig coupled reaction .The structures of the two compounds were characterized by mass spectrum and 1H NMR.Stimulated by ultravio-let light,the maximum emitting wavelength of M 1 is 447 nm in the range of blue fluorescence , which means it is suitable for blue organ-ic light-emitting material.M2 has no obvious fluorescence in the wavelength of visible light , which can be explained that as that eletron-withdrawing carbonyl inhibites π-π*transition and eventually leads to fluorescence quenching .
