Matrix order influence on the non-linear optical properties of dispersed chromophore-azopolymer systems

AbstractAzopolymers with moderate non-linear optical (NLO) response are used as host matrices for a highly efficient molecule. The second harmonic intensity generated at room temperature by these binary systems increases noticeably by adding an irradiation step (406 nm) to the corona poling process. The free volume increase due to "trans-cis" photoisomerization of the side-chain azo moieties allows to align the NLO chromophores and causes, at least partially, this enhancement. In order to investigate the role of guest-host interactions on the NLO response, different matrix arrangements have been induced and different d 33/d. © 2012 WILEY-VCH Verlag GmbH & Co.
