Electro-optic guest-host system containing azobenzene chromophores in PMMA matrix

Abstract

A guest-host polymer system was formed from poly(methyl methacrylate) (PMMA) and the synthesized N-ethyl-N-(2-hydroxylethyl)-4-(2-cyano-4-nitrophenylazo)aniline azobenzene chromophore. Linear optical properties have been determined for thin polymer films prepared by a spin-coating method. For the film poled in a moderate electric field the value of electro-optic (E-O) coefficient was measured by a simple reflection technique proposed by Teng and Man. © 2009 Photonics Society of Poland.
