A series of heterocyclic fluorescent probe containing polyesters was synthesized by high temperature condensation polymerization technique using citrimide as initiator at 170oC in DMF. All the polyesters were characterized by IR and 1H NMR spectroscopy. The inherent and reduced viscosities were checked by Ubbelohde solution viscometer, intrinsic viscosity was measured using Huggins and Kraemer’s equations. Solubility properties of all the polyesters were checked in polar and nonpolar solvents. Density of all the polyesters was measured by pyknometer. Thermogravimetric analysis of all the polyesters was carried out in air. Unique property of fluorescence of these polyesters makes them valuable high performance material for the commercial use.
