研究了聚[2-甲氧基-5-(2’-乙基己氧基)对苯乙炔](MEH-PPV)的合成路线。采用超声合成法制备出无凝胶、完全可溶、高分子量的MEH-PPV。其数均分子量可达7.9×105,并通过红外光谱、核磁共振氢谱(1H-NMR)、拉曼光谱对产物进行了结构表征。
The synthesis route of poly [2-methoxy-5- (2’-ethylhexyloxy) p-phenylacetylene] (MEH-PPV) was studied. The non-gel, fully soluble and high molecular weight MEH-PPV were prepared by ultrasonic synthesis. The number average molecular weight of 7.9 × 105, and the product was characterized by IR, 1H-NMR and Raman spectroscopy.
