Precision Switching and Coupled Motion in a [3]Rotaxane Molecular Machine

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A [3]rotaxane, composed by two crown ether macrocycles and an axle presenting three recognition sites, is operated through both chemical and electrochemical stimuli. The position of the macrocycles is precisely controlled by sequential stimulation and the processes are fully reversible. The characterization of the system revealed the macrocycles affect

Macrocycle Breathing in [2]Rotaxanes with Tetralactam Macrocycles

The Journal of Organic Chemistry, 2010
The structural dynamics of two pairs of [2]rotaxanes were compared using variable-temperature NMR. Each rotaxane had a surrounding tetralactam macrocycle with either 2,6-pyridine dicarboxamide or isophthalamide bridging units. Differences were observed in two types of rotational processes: spinning of the phenylene wall units in the surrounding ...

Direct conversion of macrocyclic furans into macrocyclic isothiazoles

Chemical Communications, 2002
The first calixhetarenes with more than one heteroatom in the constituent rings are prepared in one step by treatment of calix[4]furan 1a and calix[6]furan 1b with ethyl carbamate, thionyl chloride and pyridine to give 2, 3, 4 and 5, 6, 7 respectively; these products have been characterised by X-ray crystallography which reveals that in 2 all eight ...

Tuning the size of macrocyclic cavities in trianglimine macrocycles

Organic & Biomolecular Chemistry, 2005
The synthesis of aromatic dicarboxaldehydes is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give trianglimine macrocycles. In particular, the scope and limitation of the reaction with regard to complete control of the cavity size of the macrocycles is discussed producing a total of ...
