Stable pseudo[3]rotaxanes with strong positive binding cooperativity based on shape-persistent aromatic oligoamide macrocycles

New aromatic oligoamide macrocycles with C 3 -symmetry bind a bipyridinium guest ( G ) to form compact pseudo[3]rotaxanes involving interesting enthalpic and entropic contributions. The observed high stabilities and strong positive binding cooperativity are found in few other host-guest systems. Six...

Description
Summary:New aromatic oligoamide macrocycles with C 3 -symmetry bind a bipyridinium guest ( G ) to form compact pseudo[3]rotaxanes involving interesting enthalpic and entropic contributions. The observed high stabilities and strong positive binding cooperativity are found in few other host-guest systems. Six-residue aromatic oligoamide macrocycles bind bipyridinium guest G to form stable, compact pseudo[3]rotaxanes with strong positive cooperativity.
