The synthesis and properties of biphenyl‐ and p ‐terphenyl‐fused o ‐carboranes are described. Aryl rings in the biphenyl and p ‐terphenyl skeletons are highly coplanar because of the presence of the o ‐carborane unit. o ‐Carborane exhibits an electron‐withdrawing character via the inductive effect, resulting in a decrease in both the HOMO and LUMO levels of oligophenyls without causing electronic perturbation.
