Abstract
In this paper, poly [(2-methoxyl-5-octyloxy) Phenylene Vinylene] (MO-PPV) was synthesized by Gilch route under ultrasonic irradiation. The molecular structure, thin film and luminescence property examined through FT-IR, SEm, AFM, UV-Vis spectroscopy and fluorescent spectroscopy, the results showed that the ‘cavitations effect’ caused by the ultrasonic irradiation not only accelerate the reaction speed but also reduce structural defects of the polymer thin film, the synthesized MO-PPV is free of gelatins which is harmful for the polymer’s thin films act as active layer in polymer light-emitting diodes (PLED).
