In this paper we study the photo-oxidation phenomenon in the structure of a PPV derivative, the poly[(2-methoxy-5-hexyloxy)- p -phenylenevinylene] - (MH-PPV), using ellipsometry and infrared spectroscopy techniques. Ellipsometric measurements were carried out in MH-PPV films previously exposed to light irradiation in air. It was observed a variation of both real and imaginary components of the refractive
在本文中,我们使用椭圆光度法和红外光谱技术研究了 PPV 衍生物聚[(2-甲氧基-5-己氧基)-对-亚苯基亚乙烯基]-(MH-PPV) 结构中的光氧化现象。在先前暴露于空气中的光照射下的 MH-PPV 薄膜中进行椭偏测量。观察到折射率的实部和虚部的变化。这些变化与乙烯基 C=C 边界被羰基 C=O 边界取代有关,如红外吸收测量所证实的那样。
