For over a decade, scientists have been trying synthesis a new form of carbon called graphene with next to no success. But researchers from the University of Colorado Boulder have finally succeeded in creating the elusive allotrope of carbon. This research fills a long-standing gap in carbon material science and opens up "brand-new" possibilities for electronics, optics and semiconductor research.
The researchers have documented their process in a study titled, “Synthesis of graphene using dynamic covalent chemistry,” published in Nature Synthesis. The creation of different carbon allotropes (forms) has long interested scientists because of the element’s versatility and usefulness in various industries.Carbon allotropes can be constructed in different ways depending on how hybrids of carbons and their corresponding bonds are utilised. The most well known such allotropes include graphite used in pencil and diamonds.
Scientists have used traditional methods to create various such allotropes over the years, including fullerene and graphene. Researchers working on these materials were awarded the Nobel Prize in Chemistry in 1996 and 2010 respectively.

For over a decade, scientists have been trying to synthesise a new form of carbon called graphyne with next to no success. But researchers from the University of Colorado Boulder have finally succeeded in creating the elusive allotrope of carbon. This research fills a long-standing gap in carbon material science and opens up brand new possibilities for electronics, optics and semiconductor research.
The researchers have documented their process in a study titled, “Synthesis of γ-graphyne using dynamic covalent chemistry,” published in Nature Synthesis. The creation of different carbon allotropes (forms) has long interested scientists because of the element’s versatility and usefulness in various industries.Carbon allotropes can be constructed in different ways depending on how hybrids of carbons and their corresponding bonds are utilized. The most well known such allotropes include graphite used in pencil and diamonds. They are created out of ‘sp2’ carbon and ‘sp3’ carbon respectively.

But unfortunately, these methods do not allow for different types of carbon to be synthesised together in any kind of large capacity and this is required for creating graphyne. Due to this obstacle, graphyne remained a theoretical material speculated to have unique electrical, mechanical and optical properties.
Researchers in the field approached Wei Zhang, the co-author of the research article, and his lab group. Zhang is a professor of chemistry at CU Boulder and studies reversible chemistry. Reversible chemistry allows bonds to seld-correct, thus opening possibilities to create new kinds of ‘lattices’ (ordered structures) like synthetic polymers that resemble DNA.
