A team of researchers affiliated with several institutions in Japan has developed a way to create catenanes and a molecular trefoil knot out of para-connected benzene rings. In their paper published ...

Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: ...

Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...

The unspoken promise of new technologies is that they will advance and enhance our picture of the world — that goes double for the ones that are specifically designed to let us look closer at the ...

Benzene is big business. A natural part of crude oil, the chemical is a starting material for plastics, drugs, detergents, and more. Yet because of the molecule’s hardiness, limited chemical pathways ...

Carbazole does not look like a superstar. It is a modest tricyclic molecule, a five-membered nitrogen-containing pyrrole ring ...
