Examples of metallocene chemical compounds, their electron counts, and applications. Credit: Takebayashi et al., 2023Dr. Satoshi Takebayashi, a researcher at the Science and Technology Group at the Okinawa Institute of Science and Technology , together with Dr. Hyung-Been Kang, a scientist at OIST’s Engineering Section, and scientists from Germany, Russia, and Japan, has successfully developed a new metallocene compound at OIST.
“Having more than 18 electrons is known to be rare because if you deviate from 18, the chemical bonds of the metallocenes start to elongate, break, and change structure. However, we added two more electrons to a 19-electron metallocene and created a 21-electron metallocene. I think most people didn’t think this was possible, but our 21-electron metallocene is stable in solution and solid states and can be stored for a long time,” Dr. Takebayashi explained.

A first for ferrocene: Organometallic capsule with unusual charge-transfer interactionsAn organometallic capsule that can reversibly assemble and disassemble in response to chemical stimuli was recently developed by chemists. Comprising ferrocene-based bent amphiphiles, this new capsule can act as a host for various types of guest molecules, such as electron acceptors and dyes. Thanks to the controllable release of its cargo, the capsule would find applications in catalysis, medicine, and biotechnology.

New ribozyme can make RNA molecules accessible for click chemistry in living cellsRNA molecules are real all-rounders. They transfer the genetic information from the DNA in the cell. They regulate the activity of genes. And some of them have a catalytic effect: just like enzymes, they enable biochemical reactions that would be difficult or impossible to occur on their own. These special RNA molecules that accelerate such reactions are called ribozymes.
