Designing Tunable White‐Light Emission from an Aurophilic Cu^I/Au^I Coordination 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-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 λex ) is generated from Cu(Me2 S)[Au(CN)2 ], a feature uncommon in such simple coordination compounds.

Efficient one-pot green synthesis of tetrakis(acetonitrile)copper(i) complex in aqueous media

“…This approach is not new and was previously used by other researchers. 27 The reaction products are poorly soluble in water that also shis the reaction equilibrium toward the desired Cu(I) complex. Nevertheless, solubility varies for different counterions, we suppose it is slightly higher for the perchlorate complex compared to the tertauoroborate and hexauorophosphate compounds that result in lower yield of the reaction in the former case.…”

Pyrene-based hyperbranched porous polymers with doped Ir(piq)2(acac) red emitter for highly efficient white polymer light-emitting diodes

“…In the past decades, white polymer light-emitting diodes (WPLEDs) have been widely recognized owing to their potential applications in large-area fullcolor and flexible displays, backlights and solid lighting sources, and their great advantages such as high stability, low price, as well as easy fabrication process, etc [1][2][3][4][5][6]. A general approach to obtain white-light emission from a single molecule or polymer is to simultaneously implant complementary blue-light emitting and orange-light emitting units [7][8][9][10] or blue-, green-and red-light emitting units in the same molecule or polymer.…”

On-Demand Electrochemical Synthesis of copper(I) Triflate and Its Application in the Aerobic Oxidation of Alcohols

“…There are two commonly used routes to produce Cu I triflate, both of which were developed in the 1970s (Scheme 1). [20][21][22][23] The first involves synproportionation of Cu II (OTf)2 and copper metal in the presence of triflic acid (HOTf). While this method is high yielding, an excess of copper metal is required and vacuum distillation to remove triflic acid and MeCN is necessary, or the product must be stored as a dilute MeCN solution with copper metal still present to avoid oxidation (Scheme 1A).…”
