structures of very large polycyclic aromatic compounds containing clefts defined by polyphenylaryl groups are described. The C2-symmetric “albatrossenes” 1,3-bis(heptaphenyl-2-naphthyl)benzene (7a) and 1,3-bis(heptaphenyl-1-naphthyl)benzene (12a), as well as brominated derivatives, were synthesized by the addition of tetraphenylbenzyne to the appropriate polyphenyl biscyclopentadienones. The 2-naphthyl
描述了包含由聚苯芳基定义的裂缝的超大多环芳族化合物的合成和 X 射线结构。C2-对称“信天翁”1,3-双(七苯基-2-萘基)苯(7a)和1,3-双(七苯基-1-萘基)苯(12a),以及溴化衍生物,由将四苯基苄添加到适当的多苯基双环戊二烯酮中。2-萘基异构体具有宽而浅的裂缝,1-萘基异构体具有深而窄的裂缝,在不同的晶体环境中观察到这些裂缝的大小发生了显着变化。以类似的方式,1,3,5-三(五苯基苯基)苯(19),直径为21 A的D3对称分子推进器,和1,3,5-三(七苯基-2-萘基)苯( 22) 分别通过加入二苯乙炔和四苯苄制备,
