A Cl− Hinge for Cyclen Macrocycles: Ionic Interactions and Tweezer–Like Complexes

open access: yesFrontiers in Chemistry, 2019
The supramolecular networks derived from the complexation of polyazamacrocycles with halide anions constitute fundamental building blocks of a broad range of modern materials.

Recent Advances in Macrocyclic and Macrocyclic-Based Anion Receptors

open access: yesSupramolecular Chemistry, 2008
The interest in anion coordination chemistry has growth enormously in the last few years. Macrocyclic and macrocyclic-based architectures are at the forefront of the development of new anion receptors. This minireview is intended to illustrate some of the goals achieved recently in this field highlighting examples appeared in the literature over the ...

Macrocyclic Organic Peroxides: Constructing Medium and Large Cycles with O-O Bonds

open access: yesChemistry
Macrocycles bridge the gap between conventional small molecules and polymers. Drawing inspiration from successful carbon heteroatom-containing macrocycles, peroxide-containing macrocycles are gaining attention for enhanced bioactivity, potential ...

Schiff base macrocycles containing pyrroles and pyrazoles

open access: yes, 2008
A double nucleophilic substitution reaction of 3,5-bis(chloromethyl)pyrazole with pyrroles generates a novel pyrrole-pyrazole hybrid building block, the pyrazole analogue to tripyrrane.

Macrocycles, Catenanes and Rotaxanes

open access: yes, 2021
Inspired by the myriad enzymes found in living organisms, supramolecular chemists have investigated the cavities of both macrocycles and the related interlocked molecules catenanes and rotaxanes as catalytic and non-catalytic sites of chemical reactions.

Synthesis of macrocycles derived from vanillin and isovanillin

open access: yes, 2001
5-10Readily available vanillin 1 and isovanillin 2 have been exploited for the first time to synthesise thia and aza-bridged macrocycles. Utilising a common approach, 1 and 2 are first converted into the corresponding key intermediates, dicholoro ...

Chemistry of selenium/tellurium-containing Schiff base macrocycles

open access: yes, 2011
This paper highlights our work to establish a new class of macrocycles based on Schiff base condensation chemistry. The chemistry of a series of azomethine macrocycles, with selenium/tellurium atoms in o-positions with respect to the C=N bond is ...
