| Abstract: | Abstract The synthesis and characterization of an epoxy-based nonlinear optical (NLO) polymer exhibiting optical transparency down to 340 nm is reported. The synthesized polymers show spectroscopic properties (NMR, IR, UV) in accordance with the proposed structures. A glass transition temperature (Tg) of 92°C and a thermal degradation temperature (Td) of 322°C were recorded. The poled polymer film exhibits stable second-order nonlinear optical activity (d33 = 4.2 pm/V) over a period of 800 hours as characterized by the temporal response of the second harmonic signal at room temperature. |
