โฆ Synopsis
Anthracene derivative 4 annelated with four bieycio[2.2.2]octeae (BCO) units was newly synthesized by the Diels--Alder reaction of BCO dimer withp-benzoquinone as a key reaction, and its electronic properties w~'e investigated. The remarkable effect of BCO annelation wasobserved in its redox belmvior, and 4 was readily transformed into stable cation radical 4 +" and dication 42 +.
