Molecular Tweezers as Synthetic Receptors: Molecular Recognition of Electron-Deficient Aromatic Substrates by Chemically Bonded Stationary Phases

Ball-, Bowl-, and Belt-Shaped Conjugated Systems and Their Complexing Abilities: Exploration of the Concave−Convex π−π Interaction

“…82 Theoretical calculations of sterically rigid macrocycles 84 predict that the concave face possesses a considerably larger negative potential than the convex surface. [85][86][87][88][89][90][91] These results suggest the electron negative nature of the concave surfaces of 13-19. Together with the host properties of the calix[n]arenes and CTVs, the rigid and sizable cavity possessing electron negative potential would be important for the high affinity for the fullerene surface.…”

A Molecular Tweezer for Lysine and Arginine

“…It is completely released into solution, as indicated by a total reversion of chemical shift changes to the peptide's free state after addition of ∼1000 equiv of DMSO. By a simple change of cosolvent composition, the complexation process can hence be switched on and off in a very mild manner. , …”

Ultrathin Cross-Linked Networks at the Interface between Oil and Water: Structure, Properties, and Preparative Perspectives

“…Molecular clips and tweezers tend to bind selectively electron deficient aromatic and aliphatic substrates. Syntheses and supermolecular properties are extensively described in several papers of Prof. Klärner. − The film-forming behavior of one of these molecular tweezers was investigated by pressure−area isotherms and Brewster angle microscopy at the air−water interface. A schematic drawing of those tweezers is shown in Figure .…”
