Embodiment 1

[0035] The synthesis method of the 2-[(2-dimethylaminophenyl)(phenyl)phosphine]-N,N-dimethylaniline copper iodide complex of the present embodiment specifically includes the following steps:

[0036] (1) Synthesis of N,N-dimethyl-2-bromoaniline

[0037] The material was synthesized with reference to previously reported literature (Bonnaventure I, Charette AB. Probing the importance of the hemilabile site of bis(phosphine)monoxide ligands in the copper-catalyzed addition of diethylzinc to N-phosphinoylimines: Discovery of new effective chiral ligands[J] . The Journal of Organic Chemistry, 2008, 73(16): 6330-6340.). Concrete synthetic steps are as follows:

[0038] In a 250mL round bottom flask, add 4.0g (23.3mmol) 2-bromoaniline, 16.1g (116.5mmol) anhydrous potassium carbonate, 7.3mL (116.5mmol) iodomethane (CH 31) and 50 mL of acetonitrile (MeCN), heated to 70°C. After stirring at 70 °C for 18 h, the reaction mixture was cooled to room temperature and extracted with 100 mL ...

Abstract

The invention relates to a 2-[(2-dimethylaminophenyl)(phenyl)phosphino]-N,N-dimethylaniline copper iodide complex and a synthesis method and the application thereof. The synthesis method comprises thefollowing steps: firstly, enabling 2-bromoaniline and methyl iodide to be in a substitution reaction to produce N,N-dimethyl-2-bromoaniline, and then enabling the N,N-dimethyl-2-bromoaniline and n-butyllithium to be in reaction in a tetrahydrofuran solution to produce aryl lithium; continuing to enable the aryl lithium and dichlorophenylphosphine to be in reaction to produce a ligand 2-[(2-dimethylaminophenyl)(phenyl)phosphino]-N,N-dimethylaniline (ppda), and finally enabling the ppda and cuprous iodide to be in reaction in a dichloromethane solution to obtain a target product. When the synthesis method is used for synthesizing the target product, the yield is high and reaches 72%, and the synthesis method is simple and easy to operate; in addition, the target product has a dual-emissioncharacteristic, can be used as a light-emitting material for assembling an OLED, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of luminescent materials, more specifically, the invention relates to a 2-[(2-dimethylaminophenyl)(phenyl)phosphine]-N,N-dimethylaniline copper iodide complex substances and their synthesis methods. Background technique [0002] Compared with mononuclear and dinuclear cuprous complexes, multinuclear cuprous clusters often have the characteristics of thermochromic luminescence (Luminescence thermochromism) and dual emission (Dual emission). In cuprous complexes, there are various ways of luminescence, including local excitation (LE), charge transfer (Chargetransfer, CT) transition and cluster center (Cluster centered, CC) luminescence. Xu and co-workers report a tetranuclear cuprous iodide cluster complex containing oxafluorene bisphosphine ligands, the copper iodide cluster has a cubane-like structure, and its electroluminescence contains the blue TADF Combined with the luminescence of orange-red clusters,...
