The reaction of 9-{[<i>N</i>-<i>n</i>-propyl-<i>N-</i>(diphenylphosphino)amino]methyl}anthracene (<b>1</b>) with Au(SMe<sub>2</sub>)Cl yields complex <b>2</b> with an arm-opening configuration. The latter is treated with AgClO<sub>4</sub> to form
complex <b>4</b> and then respectively reacted with acetonitrile, pyridine,
and triphenylphosphine sulfide to afford novel gold(I) η<sup>2</sup>-arene
complexes <b>3a</b>−<b>c</b>, which have arm-closing configurations and feeble
or weak fluorescence emissions. The observation can be attributed
to charge transfer from the anthracene unit to the Au<sup>+</sup> ion. When
the solution of <b>3a</b> or <b>4</b> in CH<sub>2</sub>Cl<sub>2</sub> was added with 1 equiv of Ph<sub>3</sub>P,
complex <b>5</b> with the arm-opening configuration was formed and
strong emission was restored.
