Researchers create molecule that may pave means for mini-transistors — ScienceDaily


Researchers at Lund College in Sweden have succeeded in growing a easy hydrocarbon molecule with a logic gate perform, much like that in transistors, in a single molecule. The invention may make electrical elements on a molecular scale doable sooner or later. The outcomes are revealed in Nature Communications.

Manufacturing very small elements is a vital problem in each analysis and improvement. One instance is transistors — the smaller they’re, the quicker and extra vitality environment friendly our computer systems grow to be. However is there a restrict to how small logic gates can grow to be? And is it doable to create electrical machines on a molecular scale? Sure, maybe, is the reply from a chemistry analysis crew at Lund College.

“We’ve developed a easy hydrocarbon molecule that modifications its type, and on the similar time goes from insulating to conductive, when uncovered to electrical potential. The profitable formulation was to design a so-called anti-aromatic ring in a molecule in order that it turns into extra sturdy and might each obtain and relay electrons,” says Daniel Strand, chemistry researcher at Lund College.

Many natural molecules encompass fragrant benzene rings, ie flat rings made up of six carbon atoms. A easy instance is graphene. Nonetheless, such molecules don’t change properties or form if subjected to electrical potential. Due to this fact, the analysis group selected to take a look at hydrocarbons made up of rings with eight carbon atoms. These are anti-aromatic and bent right into a tub-shape. If two electrons are injected into such a molecule, it flattens and goes from insulating to conducting — a perform much like that of a transistor switching from 0 to 1.

“A novel facet of the molecules is that they’re so easy. They solely consist solely of carbon and hydrogen atoms which makes them simpler to provide synthetically,” says Daniel Strand.

The invention means researchers can now take into consideration find out how to develop each electrical switches and new mechanical techniques on the single-molecule degree utilizing anti-aromatic hydrocarbons.

“Molecules that change type in response to electrical potential result in thrilling potentialities. One can think about energy-efficient pc architectures and sooner or later maybe electrical machines on a molecular scale,” concludes Daniel Strand.
