Problems solved by technology

[0005] At present, the luminous efficiency and thermal stability of Cu(I) complex luminescent materials are not high enough, and RGB three-color materials with superior performance are scarce, which is still a key problem restricting their application in important fields such as organic electroluminescence.
For example, Cu(I) complexes have been used as orange / yellow phosphorescent materials for a long time, but their performance cannot meet the requirements

Embodiment 1

[0031] The new crystal form Cu(I) complex [Cu(2-QBO)(PPh 3 ) 2 ]PF 6 Preparation of:

[0032] A. Weigh 0.3mmol of 2-QBO and 0.6mmol of PPh 3 Placed in a 25ml polytetrafluoroethylene reactor;

[0033] B. Measure 3ml of absolute ethanol and pour it into the reactor, then measure 7ml of distilled water and pour it into the reactor;

[0034] C. Weigh 0.3mmol of Cu(CH 3 EN) 4 PF 6 , placed in the reactor;

[0035] D. Seal the reaction kettle, heat it from room temperature to 110°C, keep the temperature constant for 3000min, then slowly cool down to room temperature at a rate of 1.11°C / h, dry the obtained precipitate, and obtain a large number of yellow flaky crystals.

Abstract

The invention discloses a Novel crystal-form Cu (I) complex luminescent material adopting benzoxazolyl quinoline with a novel crystal form and a preparation method thereof. The phosphorescent complex is obtained by complexing cuprous salt and ligand, the molecular structure is [Cu(QBO(PPh3)2]PF6, wherein PPh3 and QBO are electrically neutral ligand triphenylphosphine and 2-(2-benzoxazole) quinolone. The complex has the advantages of easiness in purification and high luminous efficiency of micromolecules as well as high thermal stability. The material is obtained through solvothermal reaction of Cu(CH3CN)4PF6 and the ligand in an ethanol and water mixed solvent to, has the advantages of simple and convenient technology, simple equipment, easiness in getting of raw materials, low cost and the like, can be used as a photoluminescent yellow light material or a luminescent layer phosphorescent material in an electroluminescence device formed by multiple layers of organic materials.

Description

technical field [0001] The invention relates to the field of luminescent materials, in particular to the fields of Cu(I) complex luminescent materials and electroluminescent materials. Background technique [0002] Nowadays, photons are increasingly replacing electrons as the carrier of information. As the technical support of information science, photonics, photochemistry and photonic materials have attracted more and more attention from the scientific and technological circles. Among them, Ir, Pt, Ru, Re, Os and other noble metal complexes and organic compounds have been widely concerned as a new type of luminescent material. However, these transition metals are expensive, low in content, and difficult to mine, which limits their large-scale application in real life and production to a certain extent. Therefore, it is very important to find new and cheap photoelectric functional materials of metal complexes. Compared with precious metals, copper has the advantages of che...
