1,3-Diradicals Embedded in Curved Paraphenylene Units: Singlet versus Triplet State
09 Jun 2021
Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more — but how do these curved systems change when new components are introduced? Researchers based in Japan found that, with just a few sub-atomic additions, the properties can pivot to vary system states and behaviors, as demonstrated through a new synthesized chemical compound.

The generation of alkyl radicals was achieved by direct visible-light excitation of the organoborate complex, which was designed and synthesized from “boracene,” which has a boron atom in the tetracene-like skeleton. The alkyl radicals thus obtained could be used as a carbon source for chemical reactions, enabling the synthesis of complicated/bulky organic compounds. The present study offers a new protocol for organic synthesis, which is expected to accelerate e.g. drug discovery.
