Novel naphthalene derivative 4 annelated with four bicyclo[2.2.2]octene frameworks was synthesized. X-ray analysis showed that the acene core of 4 deviates from planarity. The remarkable effect of annelation was observed in its oxidizability as revealed by cyclic voltammetry, and 4 was readily conve
