A series of copolyesters were prepared from a dicarboxylic acid, curcumin analogues (monocarbonyl) and thymol blue 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
