Abstract

Although angular-shaped naphthodifurans, naphtho[1,2-b;5,6-b′]- and naphtho[2,1-b;6,5-b′]-difuran, are formally isoelectronic with chrysene as their thiophene counterparts, naphtho[1,2-b;5,6-b′]- and naphtho[2,1-b;6,5-b′]-dithiophene, the HOMO energy level of naphthodifurans is much higher than those of naphthodithiophenes and chrysene. The difference in electronic structure in the ground state can be explained by distinct electronic perturbation from the outermost aromatic rings.
