| Friedel-Crafts acylation reaction was adopted to sythesize XXXXXX, using Anhydrous Aluminium Chloride as catalyst and the yield was 70%. Fourier Transform Infrared Spectroscopy, nuclear magntic resonance, gel permeation chromatography and thermal analysis, etc were used to characterize its structure and characteristic. According to thermogravimetric analysis, it had a weight loss of 5% at 520℃, which showed its high thermal stability and wide application prospect. |

| With anhydrous aluminum chloride as a catalyst and Friedel-Crafts acylation ×××××× was synthesized ,including a yield of 70%.By using Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, gel permeation chromatography and thermal analysis, and so on ,we characterized its structure andproperties. According to TGA, we knew that 5% weight loss corresponding to the temperature of 520 ℃,and it has higher thermal stability and broad prospects for application. |
