Ion-pair Recognition by Ditopic Macrocyclic Receptors
Over the past thirty years, a large number of macrocyclic receptors have been synthesized and evaluated for their abilities to bind cations. More recently, increased attention has been directed towards receptors for anions. Many of these synthetic receptors are uncharged molecules and operate in organic solvents. Under these conditions the target salts exist as associated ion-pairs which can hi...
متن کاملIndole-based macrocycles as a class of receptors for anions.
The development of synthetic receptors and chemosensors for anions has attracted much attention in recent years as the fundamental role of anions in biological and chemical processes has become increasingly understood. Biomacromolecules such as sulfate-binding proteins and a CIC chloride channel make use of hydrogen bonds as a major driving force to bind or transport anions through cell membran...
متن کاملConvergent heteroditopic cyclo[6]aramides as macrocyclic ion-pair receptors for constructing [2]pseudorotaxanes.
A strategy of using amide groups as the only functionality was developed to construct convergent heteroditopic cyclo[6]aramides that are able to strongly bind dibutylammonium chloride in chloroform (>10(5) M(-1)), leading to the formation of [2]pseudorotaxanes.
متن کاملTailoring macrocycles for metal ion binding
Absrract: We have been concerned with the development of alternate strategies for achievinc; metalion recognition. An important aspect of this research has been to investigate meta! ion complexation over a range of related macrocycles, incorporating different macrocyclic rhg sizes, donor atom set combinations and/or degree of ring substitution and to search for stability rrnxima at different po...
