A new synthetic approach to novel polymers exhibiting large electrooptic coefficients and high thermal stability
The Stille coupling reaction was explored to synthesize novel polymers with a pending NLO chromophore exhibiting a large mu beta value but high chemical sensitivity. This approach enabled the synthesis of aromatic polyimides through the careful design of dibromo monomers bearing NLO chromophores. The resulting polyimide Nas shown to possess a glass transition temperature of 170 degrees C and a large electrooptic coefficient.
