Description

white crystals

Diphenylacetylene is the chemical compound C6H5C≡CC6H5. The molecule consists of phenyl groups attached to both ends of an alkyne. It is a colorless crystalline material that is widely used as a building block in organic synthesis and as a ligand in organometallic chemistry.

Biphenylacetylene is an arylacetylene that is acetylene in which the hydrogens are replaced by phenyl groups. It has a role as a fluorochrome. It is an arylacetylene and a member of benzenes.
