Abstract

A purple-light organic luminescent material and its preparation method relate to an organic luminescent material and its preparation method. According to the invention, low brightness and luminous efficiency of a present purple-light organic luminescent material are solved. The molecular formula of the product provided by the invention is C34H44N10Cd2O13S2. The method for preparing the purple-light organic luminescent material comprises the following steps: 1, preparation of 4-[(8-hydroxy-5-quinoline)azo]benzene sulfonic acid; and 2, preparation of a coordination polymer: respectively dissolving a ligand and cadmium chloride in a solvent, mixing ethene diamine into the solvent, stirring for 1h at room temperature, putting into a reaction vessel having a teflon inner liner, using temperature programming to 100 DEG C, and standing for 100 hours to obtain a golden yellow tabular crystal. The product prepared by the method provided by the invention is a single crystal with an intact crystal form. The purple-light organic luminescent material prepared in the invention appears a purple fluorescent light through a luminescence property test, and also has high heat stability and a good film forming characteristic. The yield of the product prepared by the method is high and reaches to more than 40%.

Description

Technical field [0001] The present invention involves organic luminous materials and their preparation methods, and it is specific to one type 4- [(8-hydroxyl-5-pyrine) pupitzonic acid cadmate and its preparation methods. Background technique [0002] Because the luminous mating parts containing the nitrogen ligand has good performance and potential application prospects in sensor technology, optical chemistry, and electrochemical luminous materials, it has attracted people's attention and has become a hot spot for research.Researchers synthesized a large number of cadmium -containing metal matched matches, especially cadmium -containing matches, and studied their luminous performance. Studies found that the electronic impact of the size of the ligand π co -system and the electronic impact of the ligand substituent is regulating.An important factor in the luminous performance of the complex; such as X. FENG et al. In 2010 reported a series of puppet nitrogen matched computers.'-A...
