Lithium acetylide

Web22 jan. 2024 · Phosphorescence colors of cyclodextrin-based insulated Pt–acetylide complexes were tuned by the molecular engineering of the chromophores. A series of Pt complexes bearing various acetylide ligands, including heteroaromatics, were prepared via self-inclusion of the linked macrocycles with the complexes. The decline in the inclusion … Lithium carbide, Li 2C 2, often known as dilithium acetylide, is a chemical compound of lithium and carbon, an acetylide. It is an intermediate compound produced during radiocarbon dating procedures. Li 2C 2 is one of an extensive range of lithium-carbon compounds which include the lithium-rich Li 4C, Li 6C 2, Li 8C 3, Li 6C 3, Li 4C 3, Li 4C 5, and the graphite intercalation compounds LiC 6, LiC 12, and LiC 18. Li 2C 2 is the most thermodynamically-stable lithium-rich …
