本文着重研究了分子对称性和异构化对基于N-苯基咔唑封端的苯基乙烯基衍生物发光性能的影响。我们设计并合成了三个以N-苯基咔唑为单芳基的异构体10-(芳基乙烯基)菲，它们的2-，3-或咔唑-9-基苯基位置相连，并研究了它们的光学和电致发光性质，并与类似的9，10-双(芳基乙烯基)菲进行了比较。结果表明，与双N-苯基咔唑类似物相反，三个单苯基咔唑封端的异构体虽然具有扭曲的π主链和磨削诱导的非晶化，但既没有聚集诱导发射，也没有机械荧光变色。结果表明，单取代能显著蓝移发射光谱，大大提高电致发光性能，并伴随着显著的同分异构体效应。这一发现表明，改变分子取代模式可以有效地改变和调节发光性质，从而极大地拓宽候选分子在光学和光电子领域的应用范围。
This paper focuses on effects of molecular symmetry and isomerisation on light-emitting properties based onN-phenylcarbazole-capped anthrylvinyl derivatives. We have designed and synthesized three isomeric 10-(arylvinyl)anthracenes withN-phenylcarbazole as the mono aryl moiety whose 2-, 3-, or carbazole-9-yl-phenyl positions are linked, and their optical and electroluminescence properties are investigated and compared with analogous 9,10-bis(arylvinyl)anthracenes. The results showed that, contrary to the dualN-phenylcarbazole-capped analogues, the three monoN-phenylcarbazole-capped isomers have neither aggregation-induced emission nor mechanofluorochromism although they are characterized by twisted π-backbone and grinding-induced amorphization. It is observed that the mono substitution can significantly blue-shift the emission spectra and greatly improve the electroluminescence performances, accompanying by the remarkably isomeric effect. This finding demonstrates that changing the molecular substitution patterns could effectively alter and tune the light-emitting properties to greatly widen the scope of molecular candidates applicable in optical and optoelectronic fields.
