Abstract

The title compound, C24H14N2, is a rigid-rod terminal dialkyne exhibiting extended π-conjugation through the heteroaromatic linker unit in the backbone. There is an intermolecular C—H⋯N close contact between one of the terminal alkyne groups and one of the N atoms, with a C⋯N distance of 3.374 (3) Å. Intermolecular interactions are also present between the alkynyl H atoms and C[triple-bond]C groups.
