相转移催化合成对苯乙炔聚合物(PPV)发光材料中间体1,4-二乙氧基苯的研究(PartⅠ)
Study on synthesis of p-phenylene vinylene polymer (PPV) photoluminescent material intermediate of 1,4-diethoxybenzene by phase transfer catalytic method
摘要
Abstract
In recent years Dialkoxyl substituted p-phenylene vinylene polymer (PPV) photoluminescent function materials were widely applied in LED(LCD) TV, computer, electrical equipments and aircraft color LED(LCD) displays, in this research we used different catalysts to synthesize Dialkoxyl substituted p-phenylene vinylene polymer (PPV) photoluminescent function materials intermediate of 1,4-Diethoxybenzene by phase transfer catalytic method, 1,4-Diethoxybenzene was synthesized using hydroquinone and diethyl sulfate in toluene solvent in the presence of sodium hydrate and catalyst HA-1, by using different phase transfer catalysts, under conditions of reaction temperature of 60-65 °C and reaction time of 3. 0 h, the product's yield was over 84%. The different catalysts usages and reation times were optimized and discussed, the product's IR spectra, NMR Spectra have been characterized and discussed in detail.关键词
