A Tetraazapentacene-Pyrene Belt: Toward Synthesis of N-Doped Zigzag Carbon Nanobelts.

Herein, we report a new design of N-doped zigzag carbon nanobelt, which is a structurally defined fragment of N-doped carbon nanotubes, and studies toward synthesis of it. As its synthetic precursor, a tetraepoxy nanobelt consisting of tetraazapentacene and pyrene subunits is successfully synthesized by taking advantage of a "C"-shaped building block. This tetraazapentacene-pyrene nanobelt is identified with single-crystal X-ray crystallography, and its electronic structure is studied with computational and experimental methods.
