AI Article Synopsis

  • The study introduces a new approach to improve organic macrocyclic hosts by enclosing them in a larger ML cage, creating host-in-host complexes.
  • The macrocyclic hosts, like cyclotriveratrylene and calix[8]arene, benefit from enhanced orientations which boost their ability to recognize other molecules.
  • The structural analysis through X-ray techniques allows for observation of how these hosts encapsulate guest molecules within the highly crystalline ML cage.

Article Abstract

This study reports a method for enhancing the functions and properties of traditional organic macrocyclic hosts by fully encapsulating them within a large ML cage to form host-in-host complexes. Within the cage host, the macrocyclic organic hosts with electron-rich aromatic rings, such as cyclotriveratrylene and calix[8]arene, adopt specific orientations enhancing their inherent molecular recognition abilities. Due to the high crystallinity of the ML cage, the guest encapsulation behavior of the host-in-host complexes can be observed by X-ray structural analysis.

Herein, we show how the chaotropic effect arising from reduced molybdate ions in acidified aqueous solution is able to amplify drastically weak supramolecular interactions. Time-resolved Small Angle X-ray Scattering (SAXS) analysis suggests that molybdenum-blue oligomeric species form huge aggregates in the presence of γ-cyclodextrin (γ-CD) which results in the fast formation of nanoscopic {Mo }-based host-guest species, while X-ray diffraction analysis reveals that the ending-point of the scenario results in an unprecedented three-component well-ordered core-shell-like motif. A similar arrangement was found by using preformed hexarhenium chalcogenide-type cluster [Re Te (CN) ] as exogenous guest.

The interaction between γ-cyclodextrin and amphiphilic p-sulfonatocalix[4]arenes was studied using NMR and isothermal titration calorimetry techniques. The results indicate that these calixarenes are able to form 1:1, 1:2, and 2:1 host-guest complexes with the cyclodextrin. The ROESY spectra suggest that the cyclodextrin binds the calixarenes through the hydrophobic alkyl chains.
