Polymeric and Hybrid Materials for Electrooptical Devices: Polar Order Dynamics.

The present contribution reviews some aspect of the exploitation of polymeric and hybrid solgel materials for optoelectronic devices. In particular a procedure addressed to experimentally investigate the order stability of systems containing NLO dipolar molecules will be discussed. A figure of merit, allowing the comparison among candidate systems for devices, is recognized in the RT d33 decay time value. Its relation with glass transition temperature of a series of similar polymeric systems is reported. Moreover, a hybrid solgel system containing electro-optic active molecules is shown.
