| Abstract: | Three samples (a), (b) and (c) of luminescent Eu-containing copolymer (NaEu(III)-TTA-PSAA) were synthesized through the reaction of copolymer of acrylic acid and styrene (Mw = 3000) with metalorganic complex (NaEu(TTA)4) obtained from Eu and thienyltrifluroacetone. These samples of coordination polymers were characterized by FTIR, UV and XPS, and their composition and structures were determined. The results of electrical conductivity methods and elemental analysis indicated that there were different compositions and structures of these coordination polymers in different pH. The results of elemental analysis also showed that the content of Eu3+ in sample (a), (b) and (c) was 11.89%, 12.55% and 13.41%, respectively. |
