Halide enhancement of the luminescence of Cd10S4 thiolate clusters
Abstract
New halide-substituted cluster anions [Cd10S4X4(SR)12]4– (R=Ph, X = I, 2a; R = p-MeC6H4, X = I, 3a or Br, 3b) of the [Cd10S4(SR)16]4– family have been prepared and characterized; investigations of their luminescence show that the introduction of the halide groups produces red shifts and significant enhancements in their emission intensities.
