The structures of the polymers were characterized by means of FT-IR, 1H NMR spectroscopy and elemental analysis. The experimental results show a good agreement with the proposed structures. TGA measurement exhibits that the polymers possess good thermal stabilities with high decomposition temperatures（T5 400 ℃）. Due to the photo-induced intramolecular charge-transfer（ICT） of fluorenone-based polyimines, these polymers show significantly strong photonic luminescence in N,Ndimethylacetamide.展开更多

The structures of polymers are characterized by means of FT-IR, 1H NMR spectroscopy, and elemental analysis. The results show an agreement with the proposed structures. DSC and TG measurements show that polymers possess high glass transition temperature (T g>170°C) and good thermal stability with high decomposition temperatures (T D>450°C). These novel polymers also exhibit good mechanical behaviors and good solubility.展开更多
