Molecular models for conduction in organic crystals with stacked π systems is a description, of syn ‐sesqui‐ and ‐sesterbenzobicyclo[2.2.2]‐octene (structure of the latter in figure on the right) and their not yet synthesized higher homologues. The distances between the benzene rings are shorter than their van der Waals distances, so that extended molecular orbitals arise from overlapping of the benzene π orbitals.
