The Synthesis And Characterization Of Anthracene-Type Electroluminescent Liquid Crystal Materials

Anthracene has a high fluorescence quantum efficiency.When the 9,10 or other carbon atoms are replaced by the modified group,a variety of luminescent materials can be achieved.Anthraquinone-type electroluminescent materials has become an important category in the organic electroluminescent material.In this paper,a number of anthracycline compounds are designed through the Wittig-Horner reaction and selecting a suitable catalyst.These reactions include:the reduction of nitrobenzaldehyde to aminobenzaldehyde;the synthesis of 9,10-dichloro-methyl-anthraquinone under the conditions of hydrogen chloride gas;the synthesis of 9,10-bis phosphite methyl anthracene with 9,10-dichloro-methyl-anthraquinone and Trimethoxy phosphorus.They are characterized through a series of NMR,IR and so on.The purpose of this paper is to synthesize such compounds connected to the silicone polymer material,and to make it has fluorescence properties,even liquidcrystallinity,which can be applied to agriculture, industry,medicine and so on. This paper also synthesized 2,2'-bis[p-(β-hydroxy-ethoxy-) phenyl] propane methacrylate double.With bisphenol A and chlorine ethanol as raw materials reacted t by the Williamson reaction o make intermediate 2,2'-bis [to-(β-hydroxy-ethoxy-) phenyl]propane.Then under the conditions of p-toluene sulfonic acid as catalyst,p-hydroxyanisole as inhibitor,benzene with water water to prepare the garget products by direct esterification.
