Four kinds of polymeric β‐diketone compounds, including poly(vinylbenzyldibenzoylmethane)(1), poly(vinylbenzylacetoacetone)(2), poly(vinylbenzyl‐2‐thenoyltrifluoroacetone)(3) and poly(p‐benzoylacetylstyrene)(4) were synthesized. And then polymeric β‐diketone‐europium(III), ‐terbium(III), ‐samarium(III), ‐dysprosium(III), ‐europium(III)‐gadolinium(III), ‐terbium(III)‐gadolinium(III), and ‐europium(III)‐terbium(III) chelates were also synthesized. The chelate structures were confirmed. The influence of the structure on the fluorescence properties was investigated. The fluorescence intensity of polymeric rare‐earth metal complexes is closely related to the ligand and metal content. Polymeric complexes possess a higher fluorescence stability than that of corresponding low‐molecular‐weight complexes.
