were easily synthesized from nonvolatile arsenic
precursors. Diiodoarsine was generated in situ and reacted with titanacyclopentadienes
to give 2,5-diarylarsoles. The structures and optical properties were
studied in comparison with those of 2,5-diarylphosphole. It was found
that the arsoles were much more stable in the air than the phosphole.
Single crystal X-ray diffraction revealed the arsenic atoms adopted
a trigonal pyramidal structure, reflecting on the s-character of the
lone pair. The obtained 2,5-diarylarsoles and 2,5-diarylphosphole
showed intense emission in solutions and solid state. In addition,
the optical properties were controlled by transition-metal coordination.
