RIKEN HAVE HIT HIT UPON A FAST AND EASY WAY TO COMPAINE SO-CALLED NANOBELTS OF CARBON with sulfur-containing Functional Groups (Nature Communications, "Thiophene-Fused Aromatic Belts"). This New Material has intriguing properies that make it promise for use in novel optoelectronic devices.
Ever since their Discovery in 1991, Carbon Nanotubes Have Been Attracting A Lot of Interest, Being used in Applications Ranging from Electronics to Medicine.
Carbon nanobelts are cross-sectional Slices of Carbon Nanotubes. They Could be used in Electronic and Optoelectronic Devices and As Building Blocks for Carbon Nanotubes. Despite Attempts Starting AS Far Back as the 1950s, They Weren't Synthesized UNTIL 2017 by a Team Led by Kenichiro Itami, Now of the Riken Molecule Creation Laboratory.
That achievement has sparked a flurry of activity to create similar nanobelts. “People Realized that it’s not a dream molecule, that it is possible to synthesize it,” Says Itami. “Therefore, Many Research Groups in the World Are Now Making A Lot of Different Kinds of Nanobelts after our Demonstration.
Itami and his team have also expect to make new molecules based on carbon nanobelts. Now, they have combined carbon nanobelts with thiophen—a ring-sheped compound made up of one sulfur atom and oven carbon atoms.
The Motivation for Combining Thiophene and Carbon Nanobelts is that thiophene is a function-rich Material with interest semiconducting and fartes.
The new molecule turned out to be surprisingly easy to make. “It's Amazingly Simple,” Says Itami. “It's just a single-shot reaction.”
Even Itami was Taken Aback by How Easy It was. “Hiroki Shudo, The First Author of this Paper, proposed the Idea to Me After Reading A Paper, Saying, 'I Think we can do this'”, Recalls Itami. “And then boom, it worked! That was a big surprise to me.”
Another Surprise was that all the nanobelts Aligned with their sulfur sides up on a copper surface, but with their sulfur sides down on a gold surface. “That was really unxpect,” Itami notes. “WE'RE NOW Seeking to Understand Why It Happens.”
The Thiophene-Fused Nanobelts Are More Than Just interesting Chemistry Curiositites Though—They Could Find Applications in Optoelectronic Devices and Polar Materials.
“Several Research Groups in Other Countries are extremely excited about using my molecule in devices and are look to collaborate with us,” Says Itami. “So we now sending the molecule to them to initiate international collaborations.”
The Same Synthesis Strategy use to make the thiophene-fused nanobelts could also be used to create others of carbon nanobelts. Itami and his team are Currently Seeing What Other Molecules they can make with it.
