Designing Tunable White-Light Emission from an Aurophilic CuI/AuICoordination Polymer with Thioether Ligands

Abstract 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⋅⋅⋅Au interactions, and Cu‐SR 2 , 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 λ ex ) is generated from Cu(Me 2 S)[Au(CN) 2 ], a feature uncommon in such simple coordination compounds.
