Conjugated Nanobelts Based on N -Hetero[(6.) m 8] n cyclacene

Year: 2024

Type: article

Abstract: This study introduces a novel design of N-doped conjugated nanobelts, derived from a specific structural unit found in carbon schwarzites, a type of negatively curved carbon allotrope. The successful synthesis of these nanobelts was achieved using a flexible curved building block in a condensation reaction with ortho-quinones. The electronic structure and aromaticity of the diazatetracene-based nanobelt were investigated and compared with diazatetracene dimers through a combination of computational and experimental methods, revealing the influence of macrocyclization on these attributes. Notably, the diazatetracene-based nanobelt encapsulates C70 in toluene with a high binding constant of (2.8 ± 0.2) × 105 M−1, demonstrating significant selectivity against C60. X-ray crystallographic analysis indicated that the nanobelt adjusts its rhombus cross section to enhance host–guest interactions when accommodating C70.
