Embodiment

[0025] Dissolve 25 g of analytically pure 8-hydroxyquinoline in 100 mL of absolute ethanol, add NaOH solution (50 g of NaOH dissolved in 70 mL of deionized water), mix well and cool, then add dropwise chloroform (25 mL, drop over 1 hour). After the chloroform was added dropwise, the temperature was raised and stirred under reflux for 18 hours. Evaporate excess chloroform and ethanol on a rotary evaporator, dissolve the remaining residue in 600mL deionized water, adjust the pH value to 5-6 with dilute hydrochloric acid, a precipitate is formed, filter it with suction and wash it with deionized water, and remove the precipitate The material was dried in an oven at 80°C. Grind the dried solid into powder, extract with petroleum ether with a boiling range of 90-120°C for 48 hours in a fat extractor, cool the extract, collect the precipitate by filtration, and recrystallize with absolute ethanol. 5-Formyl-8-hydroxyquinoline is obtained. The results of mass spectrometry are shown ...

Abstract

The invention relates to a kind of quinoline aluminum coordinated macromolecular, particularly relates to application of 3,5-2(8-hydroxyl quinoline)-benzoic acid-aluminium coordinated macromolecular, and pertains to luminescent materials. The invention includes adding 5-acryl-8-hydroxyl quinoline and 3,5-2aminobenzoic acid at a mole ratio of 2:1 into toluol, heating reflux for over 48 hours, scrubbing with ethanol and trichloromethane respectively after filtering; adding product of previous step and adequate aluminium salt needed according to coordination ratio into ethanol or methanol, stirring, waiting the solution to be clarified. The inventive quinoline aluminum coordinated macromolecular can irradiate blue light OLED needed, and can be used in organic light emitting diode as blue light material.

Description

technical field [0001] The invention relates to the application of a class of quinoline aluminum coordination polymers, belonging to the field of luminescent materials. Background technique [0002] In 1987, Kodak Company used the organic small molecule material—tris(8-hydroxyquinoline)aluminum (AlQ) as the light-emitting layer to produce a green-emitting organic electroluminescent device (OLED). This ultra-thin Flat panel devices have the advantages of low driving voltage, high brightness, and energy saving. Organic electroluminescence display technology, as the third generation display technology, has since entered a new era and has achieved vigorous development. [0003] 8-Hydroxyquinoline metal complexes are still the most important materials in the OLED field. It can not only be used in the light-emitting layer, but also widely used as the electron transport layer material of OLED. However, because it is a small molecule, in the process of device construction, vacuum...
