Abstract

Two complementary approaches to the construction of poled, crosslinked second-order polymeric NLO materials are discussed. In the first, poly(p-hydroxystyrene) is functionalized with a nitroaniline chromophore having a protectable hydroxyl group for hydrogen bonding or epoxy crosslinking. Chromophore immobilization is most effective when crosslinks can be made directly at the chromophore substituent and when multifunctional crosslinking agents are employed. The second approach shows that matrices prepared from an aryldiamine chromophore and a bismaleimide co-monomer can achieve Tg values approaching + 240°C and exceptional SHG temporal stability.
