synthesized by Suzuki and Sonogashira coupling reactions, characterized and their structure assigned by 1H and 13C NMR spectroscopy. The spectral and photophysicalproperties of a series of symmetrically and asymmetrically disubstituted anthracene-based compounds (1–6) and of benzothiadiazole derivative 7 have been studied. All these photostable systems show high fluorescence emission and a batochromic shift
四种新型二芳基蒽衍生物(1,图5a,图5b,6)已经由铃木和Sonogashira偶联反应合成,表征和由分配它们的结构1 H和13 C NMR光谱。的串联对称和对称二取代蒽类化合物(的光谱和光物理性质1 - 6和苯并噻二唑的衍生物)7已经研究过了。所有这些光稳定系统显示出高荧光发射和吸收光谱的变色位移,其随π共轭而增加。对不良荧光化合物4进行了闪光光解测量。
