摘要

White-light emitters have attracted considerable attention due to their importance in current and future technologies. By incorporating molecular fragments that independently emit in the blue, green/yellow, and red visible regions, specifically Cu-NC, Au center dot center dot center dot Au interactions, and Cu-SR2, respectively, into a single material, new white-light-emitting systems have been targeted. With this goal, three new Cu-I/thioether-based coordination polymers containing bridging [Au(CN)(2)]-units have been synthesized and structurally characterized, and their photoluminescence properties (at room and low temperatures) have been delineated. Using this approach, white-light emission (tunable from slightly yellow to slightly blue, depending on lambda(ex)) is generated from Cu(Me2S)[Au(CN)(2)], a feature uncommon in such simple coordination compounds.
