title: Syntheses, structure, and optical properties of ladder-type fused azaborines.
abstract: [structure: see text] Ladder-type fused azaborines were synthesized. X-ray crystallographic analysis of a pentacene-type molecule shown here revealed the planarity of a fused azaborine. It was revealed by UV-vis and fluorescence spectra that such fused molecular structures are efficient for the extension of pi-conjugated systems containing main group elements.
