Robust and highly emissive copper(i) halide 1D-coordination polymers with triphenylarsine and a series of bridging N-heteroaromatic co-ligands

Abstract

Various 1D-coordination polymers with dinuclear rhombic {Cu2X2} cores (X = Br, I) were synthesized using a spontaneous evaporation method employing triphenylarsine (AsPh3) and six types of bidentate N-heteroaromatic co-ligands. The...

Pseudohalide Ions as Ligands to Tune Architecture and Luminescence of Polymetallic CU(I) Assemblies

“…Indeed, in the case of derivatives C–I , very efficient nonradiative relaxation pathways due to the vibrations lying on the connecting ligands are likely taking place, which results in a weakening of the emission efficiencies of these compounds (in addition, cuprophilic are also much more intense in derivative B than in any compound of the series C – I, which also very likely is another parameter that promotes more efficient radiative relaxation processes in derivative B ). However, all in all, the photophysical properties exhibited by the series of compounds C – I are coherent regarding those recently reported in the case of RT moderately luminescent Cu­(I) assemblies ranging from TADF in the case of the derivative D to phosphorescence in the case of the other compounds C and E – I . − ,− ,,,− …”

Synthesis and luminescent properties of three excellent yellow emissive Cu(i) complexes based on the diphosphine ligand and the diimine ligand

“…In the past period of time, the [Cu(N^N)(P^P)] + and [CuX(N)(P^P)] type complexes are capable of greatly enhancing the stability and quantum yield of the complexes. 16,17 If the radiative transition occurs within the molecule, the luminescent types can be categorized as fluorescent (FL), phosphorescent (PH), and TADF. 18,19 Due to the heavy atom effect of Cu( i ), Cu( i ) complexes readily undergo intersystem crossing from the singlet excited state to the triplet excited state, leading to phosphorescence emission in nearly all copper complexes.…”
