【Abstract】 Thioether dianhydride, 2,2 ｛4 [(4 nitrophenyl)azo]imino｝bis ethylamine(diamine monomer) were synthesized and characterized. Due to this chromophore molecule(diamine nonomer) have further polymerizable amino groups on one end of the molecule, the corresponding poly(amic acid) formed with thioether dianhydride exhibited a good solubility in common organic solvents. Decomposing temperature of the diamine chromophore in the poly(amic acid) and polyimide backbone are T d=362 ℃ and 491 ℃, respectively. These polymers are currently showing interesting potential in highly sensitive, nonlinear optical materials. [WT5HZ]更多还原
