[2]‐[Cyclohexatetracontan]‐[Cyclooctacosan]‐catenan, das erste Kohlenwasserstoff‐Catenan

Abstract: Die zweite charakteristische Flip-Flop-Anordnung ist auf das p-CD-MoleMl beschriinkt, in dem zwischen allen Hydroxygruppen 0(2), O(3) benachbarter Glucosereste intramolekulare Flip-Flop-Briicken gebildet werden (Fig. 2); die Hydroxy-H-Atome, die nicht an den Flip-Flop-Bindungen beteiligt sind, partizipieren an Wasserstoffbriikkenbindungen zu ,,externen" Hydroxygruppen.Die Bildung der Flip-Flop-Wasserstoffbriicken zwischen O(2) und O(3) wird begiinstigt durch pinen fast idealen O(2). . -0(3)-Abstand (Mittelwert… Show more

“…This point of view is supported by chemical experience, which allows us to consider suitable small fragments as building blocks for large and stable molecules, and qualitative quantum chemical knowledge, which tells us that stable molecules populate sufficiently deep potential energy hypersurface minima. It has in fact been known for more than 20 years 29 that molecular representations of the Hopf link 2 2 1 , i.e.…”
