Molecular Mobius Ladders and Related Molecules

After synthesizing the 3-rung Mobius ladder, Walba conjectured that its molecular bond graph was topologically chiral [16]. In contrast with his conjecture, he 

Liang and Mislow s idea of contracting naphthalenes can be formalized if we consider the molecular cell complex rather than the molecular graph of triple layered naphthalenophane. We obtain a cell complex G by replacing each naphthalene by a pair of cells. We shall now prove by contradiction that this mo-
