We describe the modular synthesis and characterization of several substituted N-hetero benzenacyclooctaphanes (BAOs), a new motif for heteroaromatic conjugated macrocycles. The targets were synthesized via condensation of substituted aromatic ortho-diamines with a cyclic octaketone building block in moderate to excellent yields (41–91 %). We evaluated the optical and electronic properties and the solid-state structures of the targets and discuss their properties through comparison with their linear diphenyl N-heteroacene counterparts. Colorful rings: Different N-hetero benzenacyclooctaphanes were obtained by condensations with an octaketone building block. We evaluated the optical and electronic properties of the targets and discuss their properties through comparison with their linear diphenyl N-heteroacene counterparts.
