Mono-, di-, and tri-nuclear gold(I) complexes with dansyl moiety: Synthesis, characterization, and photophysical properties

Mono-, di-, and tri-nuclear gold(I) complexes with dansyl group (dansyl = 5-dimethylamino-naphthalene-1-sulfonyl), 1–3, have been synthesized and their photophysical properties investigated. The crystal structures of complexes 2 and 3 were determined by X-ray diffraction.
