Embodiment Construction

[0110] The present invention will be further described below in conjunction with accompanying drawing:

[0111] figure 1 As shown, it is the state diagram for the preparation of the final product. The position of each part must be correct, the ratio should be proportioned, and the operations should be performed in sequence.

[0112] The amount of the chemical substance required for the preparation is determined according to a preset range, with grams and milliliters as measurement units.

[0113] The three-neck flasks, beakers, stirring rods, containers, addition funnels, water circulation condensers, etc. used in the preparation should be kept clean to avoid by-products.

[0114] On the top of the stirrer 1 is an oil bath 5, in the oil bath 5 is an oil bath oil 16, on the top of the oil bath 5 is a three-necked flask 6, on the three-necked flask 6, insert a nitrogen pipe 7 and a liquid addition funnel in turn from left to right 8. Water circulation condenser pipe 9 and air ...

Abstract

The invention relates to a synthesis method of reverse-2-(2-hydroxy styryl)-8-oxyquinoline zinc. In the method, organic and inorganic and solvent materials are used and a two-step synthesis method is adopted to first synthesize reverse-2-(2-acetoxyl group styryl)-8-acetoxyl group quinoline and then directly synthesize reverse-2-(2-hydroxy styryl)-8- hydroxyquinoline zinc by ester exchange reaction. The product is yellow powder being kelly; the color coordinate is: X is equal to 0.4312 and Y is equal to 0.4861. The purity is good up to 99.1%, the light emission performance is excellent, and the yield is as high as 91.7%. The synthesis method is advanced in process, quick and simple with two steps of synthesis, reasonable in mixing rate of all chemical substances, and accurate in process parameters, being a method for synthesizing materials with kelly light by using organic and inorganic and solvent substances.

Description

technical field [0001] The invention relates to a rapid synthesis method of trans-2-(2-hydroxystyryl)-8-hydroxyquinoline zinc, belonging to the technical field of preparation and application of organic electroluminescent materials. Background technique [0002] Since C.W.Tang of U.S. Kadak Company first reported 8-hydroxyquinoline aluminum as an organic electroluminescent material in 1987, the research on organometallic complexes with 8-hydroxyquinoline as a ligand has become the focus of attention; Due to the fact that 8-hydroxyquinoline organometallic complexes are insoluble in organic solvents, the structure of 8-hydroxyquinoline ligands can be modified, mainly by introducing large conjugated substituents at the 2-position of the quinoline ring to increase the size of the 8-hydroxyquinoline ligand. The rigid structure of the quinoline ring changes the energy level difference between HOMO and LUMO in the molecular orbital to obtain organometallic fluorescent materials with...
