有机电致红光材料4-(二腈亚甲叉)-2-甲基-6-(4-二甲胺基-苯乙烯)-4H-吡喃的合成新方法

New Method for the Synthesis of 4-(Dicyanomethylene)-2-methyl-6-[p-(dimethylamino)-styryl]-4H-pyran as Red Emitter

设计全新的路线合成了红光材料4-(二腈亚甲叉)-2-甲基-6-(4-二甲胺基-苯乙烯)-4H-吡喃(DCM)。采用具有烯烃骨架的β-苯基丙烯酸酯为中间体先引入双键,再经过三酮合环制备乙烯基吡喃。

A novel route is devised to synthesize the red emitter of 4- （ dicyanomethylene ） -2-methyl-6- [ p-（dimethylamino） -styryl ] -4H-pyran （DCM） which is used in organic electroluminescent devices. Ethyl phenylacrylate intermediate bringing a double bond was introduced first, which is subsequently transformed into triketone and then DCM was obtained with high purity.
