Abstract
The invention relates to a method for preparing novel zinc terpyridine blue fluorescent powder, which is characterized in that: 4'-(4-methoxyphenyl)-2,2':6'2''-terpyridine and a zinc salt are used as a raw materials; and a solvothermal method is adopted. The method is suitable for different zinc salts and can obtain different kinds of blue fluorescent powder with similar structures.
Description
Technical field
The present invention relates to a kind of preparation method of zinc terpyridine blue fluorescent powder, can obtain the similar fluorescent material of series structure, and remarkable advantage is arranged on fluorescence intensity by this method.Its chemical formula general formula is: [Zn (C
22H
17N
3O)
2] (Y)
2, general structure is:
Y is the negatively charged ion of different zinc salts, can be perchlorate, nitrate radical, acetate or chlorion.
Background technology
The optical information material more and more causes the concern of scientific and technological circle as the technical support of information society.Embedded photoluminescent material becomes one of important topic of current research field.Up to the present, great variety of organic oneself be used as luminescent material research.The fluorescence quantum efficiency height of small molecules organic compound, and be easy to purify, but thermostability is relatively poor relatively.The high molecular polymer Heat stability is good, but purity is difficult for improving.
The character of metal complexes promptly has the advantage of organic high fluorescence quantum efficiency between organic and inorganics, therefore the characteristics of the good stability of organic/inorganic substance again are considered to have most a class luminescent material of application prospect.In recent ten years, the discovery of complex electroluminescent material and the widespread use in organic electroluminescence device thereof make the research of complex luminescent material step into a brand-new stage.Blue light material for one of three primary colors in the luminescent material also has some problems to need to be resolved hurrily (brightness, efficient is low) at present, and many scientific workers drop into great enthusiasm aspect the synthetic and research of blue fluorescent material.For this reason this paper select for use conjugated degree better and the stronger terpyridyl of coordination ability as raw material, adopt the preparation method of solvent thermal to obtain serial novel zinc terpyridine blue fluorescent material.
Summary of the invention
The object of the present invention is to provide a kind of easy method for preparing blue colour fluorescent powder.Can obtain serial luminous intensity and the higher zinc terpyridine blue fluorescent material of luminous efficiency by this method.
