largest of these molecules, hexakis[4'-(pentaphenylphenyl)biphenyl-4-yl]benzene (4, C(294)H(198)) and hexakis[4'-(2,3,4,5-tetraphenylphenyl)biphenyl-4-yl]benzene (5, C(258)H(174)) are substructures of "phenylogous cubic graphite", and the other two, hexakis(2',3',4',5',6'-pentaphenylbiphenyl-4-yl)benzene (26, C(258)H(174)) and hexakis(2',3',4',5'-tetraphenylbiphenyl-4-yl)benzene (25, C(222)H(150)) are strongly
已经通过主要采用炔烃三聚、钯催化偶联和 Diels-Alder 反应的短合成制备了四种大的 6 倍对称聚苯烃。这些分子中最大的两个,六[4'-(五苯基苯基)联苯基-4-基]苯 (4, C(294)H(198)) 和六[4'-(2,3,4,5-四苯基苯基) )biphenyl-4-yl]benzo (5, C(258)H(174)) 是“苯基立方石墨”的亚结构,另外两个,hexakis(2',3',4',5',6' -pentaphenylbiphenyl-4-yl)benzo (26, C(258)H(174)) and hexakis(2',3',4',5'-tetraphenylbiphenyl-4-yl)benzo (25, C(222)H) (150)) 是强倾斜的六叶分子螺旋桨。化合物26的X射线晶体结构也已确定;
