Nanorings: New building blocks for chemistry

Posted by in categories: chemistry, nanotechnology, particle physics

Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear.

Recently, researchers of Karlsruhe Institute of Technology (KIT) and the University of Marburg were the first to make stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated. The researchers report their findings in Nature.

Sandwich complexes were developed about 70 years ago and have a sandwich-like structure. Two flat aromatic organic rings (the “slices of bread”) are filled with a single, central metal atom in between. Like the slices of bread, both rings are arranged in parallel. Adding further layers of “bread” and “filling” produces triple or multiple sandwiches.
