Embodiment 1

[0028] A large number of phosphorescent complex materials [Cu(BINAP)(3-apy)(CH 3 CN)](PF 6 ) Crystal sample preparation: Weigh 0.1 mmol (37 mg) of [Cu(CH 3 EN) 4 ]PF 6 , 0.1 mmol (10 mg) of 3-apy and 0.1 mmol (63 mg) of BINAP. Dissolve the three drugs in 2ml of CH 2 Cl 2 and stirred for 10 min to promote its dissolution. Subsequently, [Cu(CH 3 EN) 4 ]PF 6 Mix and react with the two solutions of 3-apy. After stirring for 10 minutes, the solution becomes light yellow and turbid; then add BINAP solution, and after stirring and reacting completely, a light yellow transparent solution is obtained. Filtration; the above solution was rotary evaporated under reduced pressure at room temperature to remove all solvents, and finally obtained a fine particle crystal product with a yield of 96% (calculated as Cu).

Embodiment 2

[0030] Synthesis of orange-yellow phosphorescent complex material [Cu(BINAP)(3-apy)(CH 3 CN)](PF 6 ) single crystal: weigh 0.1 mmol (37 mg) of [Cu(CH 3 EN) 4 ]PF 6 , 0.1 mmol (10 mg) of 3-apy and 0.1 mmol (63 mg) of BINAP. Dissolve the three drugs in 2ml of CH 2 Cl 2 and stirred for 10 min to promote its dissolution. Subsequently, [Cu(CH 3 EN) 4 ]PF 6 Mixed reaction with 3-apy two solutions, stirring for 10 minutes after the reaction is complete, the solution is light yellow and turbid; then add BINAP solution, after stirring and reaction is complete, the light yellow transparent solution is still obtained. Filtered and evaporated under reduced pressure. The obtained powder was then redissolved in CH 2 Cl 2 In the process, after filtration, the upper layer of the solution was covered with n-hexane to promote the crystallization of the product, and after standing for a few days, a large number of light pink blocky crystals were precipitated. Pick a light pink block...

Abstract

The invention discloses a crystal form high-steric-hindrance diphosphine ligand BINAP cuprous coordination complex orange phosphorescent material and a preparation method thereof. A phosphorescent coordination complex is obtained by complexing of cuprous salt and ligand, and a molecular structure is [Cu(BINAP)(3-apy)(CH3CN)](PF6), wherein BINAP refers to high-steric-hindrance electrically-neutral diphosphine ligand 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl, and 3-apy refers to neutral heterocyclic ligand 3-aminopyridine. The coordination complex has advantages of easiness in micromolecular purification and high luminous efficiency and is high in thermal stability. The material which is obtained by direct mixing reaction of Cu(CH3CN)4PF6 and ligand dichloromethane solution has advantages of simplicity and convenience in process, equipment simplicity, easiness in acquisition of raw materials, low cost and the like. The material can serve as a photoluminescence orange phosphorescent material and can also serve as a luminescent layer phosphorescent material in electroluminescence devices formed by multiple layers of organic materials.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, to the fields of photoluminescent materials and electroluminescent materials, in particular to the field of organic electroluminescent materials. Background technique [0002] With the development of science and technology, 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. Functional materials with special photophysical and photochemical properties have been studied more and more, showing attractive application prospects in electroluminescence devices (LEDs), optical sensors, nonlinear optical materials (NLOs) and other fields. Compared with precious metals, copper has the advantages of cheapness, environmental protection, and non-toxicity, and my country's reserves of copper ...
