Embodiment Construction

[0035] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0036] Reagents: All reagents are commercially available and analytically pure. Tetrahydrofuran was redistilled over sodium wire under nitrogen atmosphere to remove water before use, and benzophenone was used as an indicator. The ligand ppdq was synthesized according to the literature (X.L.Wang, J.Luan, F.F.Sui, H.Y.Lin, G.C.Liu, C.Xu, Cryst.Growth Des.2013, 13, 3561).

[0037] Instrument: The infrared spectrum adopts the BX FI-IR Fourier transform infrared spectrometer (KBr tablet) of Perkin Elmet Company of the United States. 1 H and 31 P NMR spectrum uses Varian 500MHz NMR spectrometer, uses deuterium band reagent lock field and reference, chemical shift is measured in ppm, H spectrum is measured in SiMe 4 As a standard, the phosphorus spectrum is based o...

Abstract

The invention belongs to the technical field of copper complexes, and specifically relates to a bisquinoline phenylphosphine halide cuprous (I) complex, a preparation method, an application, an OLED assembly method and a photocatalyst. The invention provides four coordination mononuclear diquinoline phenylphosphine cuprous halide complexes [CuX (ppdq)] (ppdq=8-[phenyl (8-quinolyl) phosphino] quinoline, X=I (1), Br(2) and Cl(3)). The provided complex emits blue-green to red-violet light at room temperature, and the maximum emission wavelength is 503-800nm. The three complexes have good thermal stability and good catalytic performance.

Description

technical field [0001] The invention belongs to the technical field of copper complexes, and in particular relates to a bisquinoline phenylphosphine halide cuprous (I) complex, a preparation method, an application thereof, an OLED assembly method and a photocatalyst. Background technique [0002] In the past decades, the application of transition metal complexes in organic light-emitting diodes (OLEDs) has attracted extensive attention. Especially heavy transition metals such as iridium (III) and Pt (II), etc., due to the excellent spin-orbit coupling can capture triplet emission, theoretically can obtain 100% internal quantum efficiency, which is considered to greatly improve the electrical External quantum efficiency of luminescent devices. However, the high price and low natural abundance of iridium and platinum have hindered the popularization and use of OLEDs to some extent. Selecting metals with high natural abundance and low price, such as copper complexes, as subst...
