A competitive approach to obtain functionalized polymers is described in this presentation. It consists on the use functionalized sol-gel systems, known to form excellent optical quality thin films. Usually these systems suffer of the low density of active chromophores. In this approach the chromophore concentration is significantly higher. The active NLO chromophores are oriented by corona poling technique. The kinetics of poling was studied by the spectrophotometric method.
