Abstract
The present invention discloses a preparation method of {[Co(5-amino-8-hydroxyquinoline)2].H2O}n complex with a blue light property, and relates to an organic light emitting material and a preparation method therefor. The present invention solves the problem that the existing blue light organic light emitting material is relatively low in brightness and light emitting efficiency. The molecular formula of a product provided by the present invention is C18H16CoN4O3. The method for preparing the blue light organic light emitting material comprises the following steps: preparing a coordination polymer: respectively dissolving a ligand and cobalt chloride into a solvent; then adjusting the pH of the solution to 9 by using a hydrazine hydrate solution; stirring for 30 minutes at the room temperature; putting into a glass bottle; and performing temperature-programming to 110 DEG C for 72 hours to obtain brown blocky crystals. The product prepared by the method is a monocrystal which is intact in crystal form. The prepared blue light organic light emitting material emits blue-fluorescent light according to a luminescence property test and further has relatively high thermal stability and a good film forming characteristic. The product prepared by the method disclosed by the present invention is high in yield which can reach over 40%.
Description
Technical field
The present invention relates to luminous organic material and preparation method thereof, be specifically related to a kind of 5-amino-8-hydroxyquinoline cobalt complex and preparation method thereof.
Background technology
Owing to there being the concern of good performance and potential application prospect and extremely people in sensor technology, photochemistry and electroluminescent material etc. containing the emitting complexes of azo ligands, become the focus of research.But because azo compound is extremely unstable, easily reaction in－situ occurs under certain condition, researchist has synthesized the metal complexes containing 5-amino-8-hydroxyquinoline part.This part is because 4-[(8-hydroxyl-5-quinoline) azo]-Phenylsulfonic acid azo bond when the effect of High Temperature High Pressure alkaline condition ruptures, generate Sulphanilic Acid and 5-amino-8-hydroxyquinoline two compounds, wherein, 5-amino-8-hydroxyquinoline and Co
2+ion coordination generates title complex.Researchist have studied the luminescent properties of this title complex, and research finds that the size of the pi-conjugated system of part and the electronic effect of ligand substituting base are the important factors regulating title complex luminescent properties.Although people have done large quantity research to emitting complexes, the research for the title complex containing 5-amino-8-hydroxyquinoline part has not been found so far.
