Macrocycles, Catenanes and Rotaxanes [PDF]

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.

A Multi‐Stimuli Transformational Network of Benzil‐Based Pd(II) Assemblies

open access: yesAngewandte Chemie, EarlyView.
Incorporation of a flexible and chemically reactive benzil backbone into the ligand structure allows it to access multiple conformations, enabling the formation of diverse homo‐ and heteroleptic Pd(II) assemblies with different nuclearities and topologies.

Synthesis of Spiroligomer-Containing Macrocycles [PDF]

open access: yes, 2015
We demonstrate the synthesis and characterization of the solution conformations of a collection of functionalized spiroligomer-based macrocycles. These macrocycles contain 14 independently controllable stereocenters and four independently controllable ...

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity

open access: yesAngewandte Chemie, EarlyView.
This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

New Cleft-like Molecules and Macrocycles from Phosphonate Substituted Spirobisindanol

open access: yesMolecules, 2008
We have synthetized medium-sized cyclophanes and macrocycles containingphosphonic groups, directly linked to the aromatic rings of the phanes or as pendant arms,for use as specific receptors for the selective complexation of neutral guests or ...

42-and 46-membered phosphorus-based macrocycles [PDF]

open access: yes, 2007
42- and 46-Membered phosphorus-based macrocycles were obtained in a [2+2] condensation of PhP(O)[N(Me)NH2]2 with dialdehydes. These macrocycles were isolated in a pure form after preparative thin layer chromatography and were characterized by ...

Schiff base macrocycles containing pyrroles and pyrazoles [PDF]

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.

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

open access: yesAngewandte Chemie, EarlyView.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Creating molecular macrocycles for anion recognition

open access: yesBeilstein Journal of Organic Chemistry, 2016
The creation and functionality of new classes of macrocycles that are shape persistent and can bind anions is described. The genesis of triazolophane macrocycles emerges out of activity surrounding 1,2,3-triazoles made using click chemistry; and the same
