Annelated perylenes: benzenoid molecules violating the Kekulé-structure-based cyclic conjugation models [PDF]
Journal of the Serbian Chemical Society, 2005 Several currently used models for assessing the extent of cyclic conjugation in benzenoid hydrocarbons, all based on Kekulé-type structural formulas, predict that there is no cyclic conjugation in the central, “empty”, ring of perylene and its annelated ...
