Highly Luminescent Cu^I Complexes for Light‐Emitting Electrochemical Cells

Copper(I) Complexes of Bis(2-(diphenylphosphino)phenyl) Ether: Synthesis, Reactivity, and Theoretical Calculations

“…After 8 hours the reaction mixture was concentrated to 5 mL and Et2O (5 mL) was added and allowed to stay at room temperature for 1 day to obtain colorless crystals of 1. Yield: [Cu(k 2 -P,P'-DPEphos)(κ 2 …”

“…[1][2][3][4] In recent years, there has been several reports on mixed ligand complexes containing both bis(phosphines) and polypyridyls. 5,6 These complexes have been easily synthesized by treating bis(phosphines) with appropriate metal precursors followed by the addition of N-donor ligands.…”

Alkynyl triphosphine copper complexes: synthesis and photophysical studies

“…More recently, research focus has largely shifted to the mixed phosphine-diimine complexes [Cu(NN)(PP)] n+ (n = 0, 1) of neutral and cationic nature, for which an impressive enhancement of quantum yield was demonstrated reaching as high as 90%. 5,12,16,18,23,25,28 The emission observed originates mainly from MLCT excited states that makes possible tuning luminescence parameters through electronic and stereochemical properties of the ligands that stimulated further A general common feature of the Cu(I) complexes mentioned above is a conformationally rigid chelating bidentate phosphine that brings steric bulkiness and minimizes the undesired excited state distortions. It has to be noted that triphosphine ligands have been rarely used in the synthesis of Cu(I) species with only a few reports on luminescent compounds.…”

Recent Advances in Polymer Organic Light-Emitting Diodes (PLED) Using Non-conjugated Polymers as the Emitting Layer and Contrasting Them with Conjugated Counterparts

“…LEEC is an alternative to OLED as a lightemitting device, which enjoys a simpler device architecture and fabrication procedure, because it is usually single-layered and has the ionic emitting layer spun-coated on the anode substrate. [38][39][40][41] Furthermore, air-stable cathodes (e.g., Al 40 and Ag 41 ) can be employed for LEEC devices to reduce device encapsulation cost. Ir-P4-2 and Ir-P4-5 were synthesized by nitroxide mediated polymerization (NMP) so that they had low PDIs of 1.16 and 1.17, respectively.…”
