Tetradecaphenyl-p-terphenyl was prepared in low yield by two methods: (1) Ullmann coupling of pentaphenyliodobenzene and 2,3,5,6-tetraphenyl-1,4-diiodobenzene and (2) Diels-Alder addition of tetracyclone and 1,4-bis(phenylethynyl)-2,3,5,6-tetraphenylbenzene. Its X-ray structure shows it to possess an unusual conformation with two boat-shaped benzene rings.
