Abstract

New poly(fluoro-aryl-thiazole) copolymers were synthesized through polycondensation polymerization between aryl-aldehydes (featuring naphthalene, benzene, thiophene, and biphenyl linkers) and dithiooxamide. The successful formation of the polymers was confirmed using spectroscopic techniques, including 1H and 13C NMR, solid-state 13C NMR (CP-MAS), and FTIR. Incorporating thiazole units into the polymer structure increases the sulfur and nitrogen content within the framework. This modification significantly enhances the polymers' thermal stability, as thermogravimetric analysis demonstrates. Additionally, the polymers show improved efficiency in separating Th(IV) and Al(III) ions from aqueous solutions.
