Abstract
Several organic nonlinear optical (NLO) materials possess larger second-order optical nonlinearities than their inorganic counterparts. However, the temporal stability of the NLO properties in the polymeric materials needs to be improved at elevated temperatures. The longterm NLO stability is a critical factor for possible future applications. To enhance the temporal stability, NLO moieties are usually incorporated in a high glass transition temperature (Tg) polymer which is capable of preventing the randomization of the poled (aligned) NLO molecules. Moreover, the temporal stability can be greatly enhanced when a certain degree of crosslinking is introduced.1
