The
syntheses and optical, electronic, and structural properties
of a series of bent <i>N</i>-heteroarenes are described.
The targets were obtained by condensation reactions of substituted
aromatic <i>o</i>-diamines with 1,2-naphthoquinone and 1,2-anthraquinone
in yields between 34 and 94%; naphthoquione-based products are generally
formed in higher yields
