of heterocyclic tetrahydropentacene derivatives via nucleophilic aromatic substitution reactions of bidentate nucleophiles and tetrafluoroterephthalonitrile was developed. X-ray crystallography of several products revealed that the compounds containing oxygen and nitrogen heteroatoms are highly planar and engage in π-stacking, while the compounds containing sulfur are bent and do not stack as effectively
开发了一种通过二齿亲核体和四氟对苯二甲腈的亲核芳族取代反应制备各种杂环四氢并五苯衍生物的合成方法。几种产品的X射线晶体学分析表明,含氧和氮杂原子的化合物高度平面化并参与π堆积,而含硫的化合物则弯曲且不能有效堆积。该化合物还具有高发射率,并且杂原子对发射和电化学性质具有重大影响。
