A team of chemists has made significant strides in the field of mechanically interlocked molecules (MIMs). Their work showcases the development of a compact catenane with tuneable mechanical chirality ...

Stringing together two molecular rings, each bearing four positive charges, seems like it should defy the laws of physics. After all, those laws dictate such charges repel one another, so attempting ...

Catenanes are organic compounds with ring-like molecules that are mechanically interlocked. The mechanical locking system in such molecules is so robust that they can only be disentangled via covalent ...

A new type of neutral donor-acceptor [2]-catenane, containing both complementary units in the same ring was synthesized from a dynamic combinatorial library in water. The yield of the water soluble [2 ...

Catenanes -- materials made of interlocking molecules, similar to medieval chain mail -- have proved laborious to make since their discovery 25 years ago. Now, chemists have found a way to make ...

This study is led by Prof. Wen-Bin Zhang (College of Chemistry and Molecular Engineering, Peking University & Beijing Academy of Artificial Intelligence) and Dr. Jing Fang (College of Chemistry and ...

Threads or ropes can easily be used for braiding, knotting, and weaving. In chemistry, however, processing molecular strands in this way is an almost impossible task. This is because molecules are not ...

A team of chemists from The University of Hong Kong (HKU), in collaboration with international scientists, has made significant strides in the field of mechanically interlocked molecules (MIMs). Their ...

In a new study led by Oxford University's Department of Chemistry, chemists have demonstrated the synthesis of a cyclocarbon that is stable enough for spectroscopic characterization in solution at ...
