Tailoring 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...
متن کاملAdaptive self-assembly and induced-fit transformations of anion-binding metal-organic macrocycles
Container-molecules are attractive to chemists due to their unique structural characteristics comparable to enzymes and receptors in nature. We report here a family of artificial self-assembled macrocyclic containers that feature induced-fit transformations in response to different anionic guests. Five metal-organic macrocycles with empirical formula of MnL2n (M=Metal; L=Ligand; n=3, 4, 5, 6, 7...
متن کاملIndole-based macrocycles and oligomers binding anions
Indole-based synthetic receptors which bind anions by multiple hydrogen bonds in organic solvents have been prepared. The biindole scaffold bearing two good hydrogen bond donors of indole NHs has been used as a molecular building block to construct the receptors. Incorporation of more hydrogen bond donors or acceptors increases the binding strength and selectivity toward a specific ion. Two mac...
متن کاملSynthesis, Structure and Catalytic Performance of N4-Macrocycles of Fe III and Co II for Oxidation of Hydroquinone
Macrocycles and p-benzoquinones (p-BQ) have been generally connected as potential co-synergist redox models in aerobic oxidation. To get insight for the synergist oxidation of hydroquinones (H2Q), thus, we synthesized and characterized dibenzotetraaza [14]annulene type macrocycles of FeIII and CoII metal ions and described by utilizing different examinations inc...
متن کاملPolyfunctionalized macrocycles demonstrate enantioselective and ditopic binding properties.
A pair of enantioselective, ditopic macrocycles is described; the receptors bind chiral ammonium cations in a manner that depends on the stereochemistry of the cation as well as the nature of its counter anion.
