Novel, non-linear optical fluorinated polyimides were prepared by the Mitsunobu reaction of hydroxyl-containing hetarylazo chromophores with hydroxyl polyimides. Their structures were verified by FT-IR, 1 H NMR, UV–Vis spectra, elemental analysis and gel permeation chromatography. The resulting amorphous polyimides exhibited good solubility and can be easily spin-coated into thin films with...
The novel fluorinated polyimides with side-chain nonlinear optical (NLO) chromophores were synthesized from hydroxyl polyimides, followed by the Mitsunobu reaction with NLO chromophores. Molecular structural characterization for the resulting polymers was achieved by 1 H NMR, FT-IR, UV–Vis spectra, elemental analysis and gel permeation chromatography (GPC). The polymers exhibit excellent solubility...
