Graphical Abstract
Partnerpräferenzen bei der Pseudorotaxanbildung wurden genutzt, um ein integratives selbstsortierendes System zu erstellen, das bezüglich Sequenz und Stereochemie simultan diskriminiert (siehe Bild). Es wurde gefunden, dass Calix[6]arene selektiv mit einer bevorzugten Orientierung auf Bisammonium-Achsen fädelten, selbst wenn die Strukturunterschiede zwischen den Bausteinen klein und entfernt von den Bindungszentren lokalisiert waren.

- 18The preference for endo-alkyl over endo-benzyl complexation by 1H wheels was recently confirmed[15a] by DFT calculations at the B3LYP/6-31G* level of theory, which indicated that the endo-alkyl stereoisomer was more stable than the endo-benzyl stereoisomer by 3.5 kcal mol−1.
- 19See the Supporting Information for further details.
- 20The presence of 1H⋅22+⋅1tBu heteropseudo[3]rotaxanes was excluded by means of analysis of the COSY-45 spectrum of the 1:2:2 mixture of 22+, 1H, and 1tBu (see Figure S26 in the Supporting Information). In particular, analysis of the upfield negative region of the COSY-45 spectrum revealed the presence of only one aliphatic chain (α–ε in Figure 3 and Figure S26) inside a calix cavity. These data, coupled with the signal integration, are in accordance with the presence of two equivalent calix wheels at the extremities of 22+. The presence of only one type of calix wheel was confirmed by the observation of a single AX system for calixarene ArCH2Ar groups in the 3–5 ppm region of the COSY-45 spectrum.[19] In fact, as detailed previously,[13, 15] these ArCH2Ar hydrogen atoms appear as a broad singlet for the conformationally mobile free wheel, whereas they give rise to two doublets (AX system) when the wheel is conformationally blocked by pseudorotaxane formation.
- 21The slower kinetics of threading/dethreading of a tert-butylated calix[6]arene with respect to a non-tert-butylated calix[6]arene was observed previously in equilibration experiments in CDCl3.[15a]
- 22As suggested by one referee, an additional rule can be obtained from the 1:1:2 competition experiment with the two axles 22+ and 32+ and wheel 1H. The corresponding 1H NMR spectrum (see Figure S36) clearly shows the formation of (H,H)-1H⋅22+⋅1H and thus indicates a clear preference for inner- over outer-alkyl complexation. Since this additional rule is not relevant to the development of integrative self-sorting system, it was not included in the main text.
