In this study, we investigated the effect of pressure on the formation and decomplexation of [2]pseudorotaxanes. High pressure accelerated the formation of [2]pseudorotaxanes in an aprotic nonpolar solvent (CDCl(3)/CD(3)CN) via the slipping approach

In this study, we synthesized dibenzo[22–30]crown ethers and dumbbell-like secondary ammonium salts having stoppers of varying bulk. These crown ethers formed pseudorotaxanes with the ammonium ions...

HETEROCYCLES. 68:5
Pseudorotaxanes were synthesized in this study. They comprised secondary ammonium ions and 24-membered crown ethers possessing one-four benzene rings fusing macrocycles. Kinetic and thermodynamic stabilities of the complexes were dependent on their n
