Interpolation of shared π-bonds in cyclofusene
Magnetic Resonance Imaging
Cyclofusene is a corona-condensed benzenoid whose graph-theoretic representation consists of hexacycles with exactly two non-adjacent shared II-bonds. We showed that the number of linear chains, k, is an upper bound for m, the number of shared II-bonds. Furthermore, this upper bound is achievable. In this paper, we show that given a positive even integer m < k, there exists m shared II-bonds. In other words, the number of shared II-bonds in cyclofusene has the even interpolation property. © 2005 Springer Science+Business Media, Inc.
