Preprogrammed assembly of supramolecular polymer networks via the controlled disassembly of a metastable rotaxane

Communications Chemistry, 2022
Preassembled materials are ubiquitous in our everyday life due to their readiness and functionality; an end-user simply follows instructions to assemble them and harness function. Here, metastable rotaxanes are utilized to approach preassembled materials:

Azo‐Dye Rotaxanes

Angewandte Chemie International Edition in English, 1997
The hydrophobic effect was used to assemble encapsulated azo dyes such as 1 in water. The dumbbell-shaped dyes were synthesized inside α-cyclodextrin, β-cyclodextrin, or a cyclophane to yield stable rotaxanes.

Molecular folding governs switchable singlet oxygen photoproduction in porphyrin-decorated bistable rotaxanes

Communications Chemistry
Rotaxanes are mechanically interlocked molecules where a ring (macrocycle) is threaded onto a linear molecule (thread). The position of the macrocycle on different stations on the thread can be controlled in response to external stimuli, making rotaxanes

Synthesis of a [6]rotaxane with singly threaded γ-cyclodextrins as a single stereoisomer

Beilstein Journal of Organic Chemistry, 2019
A series of hetero [4]-, [5]- and [6]rotaxanes containing both cucurbit[6]uril (CB[6]) and γ-cyclodextrin (γ-CD) as the macrocyclic components have been synthesized via a threading-followed-by-stoppering approach.

Exploring Calixarene‐Based Pseudorotaxane Architectures: Threading Ammonium Axles With an Exo‐Rim π‐Functionalized Calix[6]Arene Macrocycle

Chemistry – A European Journal, EarlyView.
This research presents a novel 1,4‐π‐functionalized calix[6]arene with enhanced interactions with dialkylammonium axles. We investigate threading behavior in CDCl3, highlighting how exo‐rim π‐functionalization affects binding affinity and stereoselectivity.
