Since PAH does not present any particular optical functionality, the main final film feature will came from the side chain DR13 azo-chromophore group due to its large nonlinear optical properties and photoisomerization capabilities. This work reports the electrooptic activity of MMADR13/DR13 LBL films, which arises from the high hiperpolarizability about the azo side chain group.528-531engAcrylic monomersAzobenzeneCationic polymerizationChromophoresCopolymerizationElectrooptical effectsAnionic polyelectrolytesElectrooptic proprietiesLayer by layer films (LbL)Methacrylic copolymerPolymer filmsTrabalho apresentado em evento10.1109/ISE.2005.1612443Acesso aberto2-s2.0-33847698981
