The invention discloses an
imidazole tri-acylhydrazone compound shown in formula I, an application of the compound as an organic light-emitting material as well as a preparation method of the compound. Four functional structure units, namely, an
imidazole group, an acylhydrazone group, a
diarylethene group and a naphthyl group, are effectively combined in one molecule, and a novel multi-functional-group
imidazole tri-acylhydrazone organic light-emitting molecule is formed. The preparation method of the light-emitting material comprises steps as follows: (1) preparation of an intermediate, namely, imidazole trimethyl
tricarboxylate; (2) preparation of an intermediate, namely, imidazole trimethyl
hydrazide; (3) preparation of a target product, the imidazole tri-acylhydrazone. The preparation method is simple and comprises few synthesis steps, raw materials are easy to obtain, the cost is low, and purification and industrialization are easy. The imidazole tri-acylhydrazone compound is stable in structure and easy to store and shows stronger
fluorescence emission under solution and
solid states. The light-emitting material is good in stability and can be applied to fields of light-emitting devices,
fluorescence sensing and the like.
