In the present study, we report the synthesis and photoluminescence properties of 4-HBPBF-Cu and HBPBF-Zn terpolymer metal complexes. These terpolymer metal complexes have been prepared using the synthesized copolymer as ligand with two transition metal ions Cu2+ and Zn2+ ions at 60 ºC. The terpolymer resins (4-HBPBF) have been synthesized by the condensation of 4- hydroxybenzaldehyde (4-HBP) and biuret (B) with formaldehyde (F) in the presence of acid catalyst and using 2:1:3 molar proportions of the reacting monomers at 126±2°C. A terpolymer composition has been determined on the basis of their elemental analysis and the number average molecular weight of this terpolymer was determined by conductometric titration in non-aqueous medium. The viscosity measurement in dimethyl sulphoxide (DMSO) has been carried out with a view to ascertain the characteristic functions and constants. The newly synthesized terpolymer resin was characterized by UV-visible
