Influência da espessura nas propriedades de absorção e emissão e na morfologia de filmes automontados de poli(p-fenileno vinileno

Abstract: . In this report, we studied the thickness effect on the optical and morphological properties of self-assembled (SA) poly(p-phenylenevinylene) (PPV) films, wich were processed with 5 and 75 layers from a PPV precursor polymer and dodecylbenzenesulfonate, and then, thermally converted at 230 °C. The increase of the film thickness yielded more intense peaks in the vibrational spectral range. The electron-phonon coupling was quantified by the Huang -Rhys factor, that shows the effects on the polymer chain mobilit… Show more
