摘要

以二羧酸、姜黄素类似物(单羰基)和苯酞染料为原料,以三乙胺(Et3N)为缩合剂,按摩尔比2:1:1直接缩合制备了9种共聚酯。所使用的二羧酸是2,6-吡啶二羰基二氯酸。采用酸催化醛醇缩合反应制备姜黄素类似物。用FT-IR对这些共聚酯进行了表征。并对合成的共聚酯的荧光特性进行了研究。此外,用热重分析(TGA)研究了这些共聚物的热稳定性。

Synthesis and Characterization of Some New Copolyester from Curcumin Mono-Carbonyl Analogues
Nine copolyesters were prepared from a dicarboxylic acid, curcumin analogues (monocarbonyl) and phenophthalene dye in the mole ratio of 2:1:1 by direct polycondensation using triethylamine (Et3N) as the condensation agent. The dicarboxylic used is 2,6-Pyridine dicarbonyl dichloride acid. The curcumin analogues were prepared by acid catalyzed Aldol condensation reaction. These copolyesters were characterized by FT-IR. The fluorescence of the synthesized copolyesters was also investigated. Furthermore, Thermo gravimetric analysis (TGA) was used to investigate the thermal stability of these copolymers.
