1,3,5-Tribromo-2,4,6-triethynylbenzene

Allyltriethoxysilane

silane coupling agent precursor

1,3,5-Tribromo-2,4,6-triethynylbenzene is a brominated aromatic compound used as a precursor in the synthesis of graphyne, a theoretical carbon allotrope. Graphyne consists of one-atom-thick planar sheets of sp and sp2-bonded carbon atoms, but its practical synthesis remains challenging and yields are limited.
