Naphthotubes: Macrocyclic Hosts with a Biomimetic Cavity Feature

Accounts of Chemical Research, 2019
Macrocyclic hosts are the principal tools used in supramolecular chemistry because they can recognize other small molecules through non-covalent interactions. However, in terms of recognition ability, known macrocyclic hosts are often not comparable to bioreceptors.

Molecularly imprinted cavities template the macrocyclization of tetrapeptides

Chemical Communications, 2008
Cavities formed using cyclic tetrapeptides (CTPs) or heat-induced conformers act as templates for cyclization; the cavities bind to linear tetrapeptides and enforce turn conformations to enhance cyclization to constrained CTPs.

Molecular Assemblies Offering Hydrogen-Bonding Cavities: Influence of Macrocyclic Cavity and Hydrogen Bonding on Dye Adsorption

Inorganic Chemistry, 2022
This work presents a set of Hg macrocycles of amide-phosphine-based ligands offering H-bonding cavities of different dimensions. Such macrocycles are shown to selectively adsorb anionic dyes followed by neutral dyes as well as Prontosil, a biologically relevant antibiotic, within their cavities with the aid of H-bonding-assisted encapsulation.

Novel π-Expanded Radialene Macrocycles with Inner Cavity

Organic Letters, 2004
[structure: see text] Polyenyne macrocycles with pi-extended [9]- and [12]radialene frameworks have been synthesized. These radialenes exhibit restricted rotation of the aromatic rings, and the D3- and D4-symmetric structures in solutions have been determined by dynamic NMR.

Tuning the Chiral Cavity of Macrocyclic Receptor for Chiral Recognition and Discrimination

The Journal of Organic Chemistry, 2008
The size and shape of the chiral cavity of a macrocyclic receptor were tuned by the alteration of the binaphthyl moiety to improve the chiral recognition/discrimination ability. For example, host 3 with the 3,5-bis(trifluoromethyl)phenyl group at the 3,3'-positions showed improved enantioselectivity for small molecules such as 2-chloropropionic acid ...

Self-assembly of novel macrocyclic aminomethylphosphines with hydrophobic intramolecular cavities

Dalton Trans., 2004
Novel macroheterocyclic tetraphosphines, namely, 1,1',5,5'-bis(arylene)-bis(1,5-diaza-3,7-diphosphacyclooctanes) 2-6, were obtained without the use of high-dilution techniques or any matrix by the reaction of bis(hydroxymethyl)organylphosphines with primary aromatic diamines containing two p-phenylene fragments linked by various one-atom bridges in a ...

Chiral Selector with Multiple Hydrogen-Bonding Sites in a Macrocyclic Cavity

Organic Letters, 2008
Chiral macrocycles with the hydrogen bond donor/acceptor sites in the cavity were synthesized and covalently bonded to silica gel to give chiral stationary phases (CSPs), which showed excellent abilities to resolve various chiral compounds, such as benzoin and Co(acac)3, in HPLC.

Disilver(I) Macrocycles:  Variation of Cavity Size with Anion Binding

Inorganic Chemistry, 2005
Reaction of the N-methylated bis(amidopyridine) ligand, LL = C6H4(1,3-CONMe-4-C5H4N)2, with the silver salts AgNO3, AgO2CCF3, AgO3SCF3, AgBF4, and AgPF6 gave the corresponding cationic disilver(I) macrocycles [Ag2(micro-LL)2]X2, 2a-e. The transannular silver...silver distance in the macrocycles varies greatly from 2.99 to 7.03 A, and these differences ...
