Toward tunable molecular switches from organic compounds

Joint press release by Hokkaido University and Kyushu University. 

Newly synthesized organic molecules can be tuned to emit different colors depending on their molecular structures in crystal form.

Molecular switches are chemicals with molecular structures that can be shifted between two or more stable configurations in response to changes in their environment. They are of great interest in the development of molecular computers, molecular machines and drug delivery systems. Compounds with conformational isomers—identical molecular formulas but different molecular structures—can make very effective molecular switches.

Researchers at Hokkaido University and Kyushu University have developed a technique to synthesize potential molecular switches from anthraquinodimethanes (AQDs), a group of overcrowded organic molecules. The study, led by Associate Professor Yusuke Ishigaki at Hokkaido University and Associate Professor Toshikazu Ono at Kyushu University, was published in the journal Materials Chemistry Frontiers.
