Carbon nitrides are compounds consisting only of carbon and nitrogen atoms. Carbon nitrides are also known as organic semiconductors with a band gap of 2.7 eV. Due to its hydrogen-bonding motifs and electron-rich properties, this carbon material is considered a potential candidate for material applications in carbon supplementation.[1]
Dicyanopolyynes are composed of a chain of carbon atoms with alternating single and triple bonds, terminated by nitrogen atoms. Although not a polyyne dicyanoacetylene (N≡C−C≡C−C≡N) otherwise fits within this series.
