Scientists at the University of Gothenburg have synthesized diamondiyne, a new carbon allotrope with a porous, tetrahedral structure. This is the first time a 3D carbon allotrope has been created, filling a gap that existed since the discovery of graphene and fullerenes. The material forms as a thin film at the interface of two liquids, using relatively inexpensive equipment, and its structure has been confirmed via electron microscopy. Diamondiyne is theorized to have interesting properties due to its porosity, potentially enabling applications in filtration, gas storage, or even as a scaffold for other materials. The researchers plan to investigate these possibilities further. This breakthrough opens up a new class of carbon materials that could have implications for sustainable chemistry and advanced manufacturing, though commercial applications are still far off.
