Formation of a hetero[3]rotaxane by a dynamic component-swapping strategy.

Reversible formation of a poly[3]rotaxane based on photo dimerization of an anthracene-capped [3]rotaxane.

We prepared a poly[3]rotaxane consisting of a ''topologically linked polymer backbone'' in one pot from readily available, modular building blocks via a dynamic polymerization strategy based on reversible anthracene dimerization.

Construction of rotacatenanes using rotaxane and catenane frameworks.

The construction of novel mechanically interlocked structures has become a topic of great current interest due to the requirements of topology and their potential application in molecular machines and devices. Rotaxane and catenane as two basic topological frameworks can be used to construct the fused structures. In the current investigation, a class of novel ammonium backbones were synthesized...

One-pot synthesis of hetero[6]rotaxane bearing three different kinds of macrocycle through a self-sorting process.

In this article, a six-component self-sorting process that involves three types of crown ether macrocycle and three types of cation guest molecule was carefully and thoroughly investigated. The six components include three kinds of crown ether, namely bis(p-phenylene-34-crown-10) (BPP34C10), dibenzo-24-crown-8 (DB24C8) and benzo-21-crown-7 (B21C7), and their corresponding cation guest molecules...

Template-directed synthesis of multiply mechanically interlocked molecules under thermodynamic control.

The template-directed construction of crown-ether-like macrocycles around secondary dialkylammonium ions (R2NH2+) has been utilized for the expedient (one-pot) and high-yielding synthesis of a diverse range of mechanically interlocked molecules. The clipping together of appropriately designed dialdehyde and diamine compounds around R2NH2+-containing dumbbell-shaped components proceeds through t...
