A special multifunctional ionic liquid compound (1‐methyl‐3‐(2‐(thiocarboxyoxy)‐ethyl)‐2H‐imidazole‐1,3‐diium bromide ( SHIL )) is used as the chemical bridge to link lanthanide beta‐diketonates and polymer resin, which are designated as Ln(L) 4 ‐ SHIL ‐ WR / MR (Ln = Eu, Tb, Sm; L = thenoyltrifluoroacetonate ( TTA ), acetylacetonate ( AA ), dibenzoylmethane ( DBM ); WR = Wang resin, MR = Merrifield resin). Among SHIL and polymer resin are assembled to form covalently bonded system through condensation reaction. Then tetrakis lanthanide beta‐diketonates are linked to SHIL through ion‐exchange reaction. Physical characterization and especially the photoluminescent performance of the multicomponent hybrids are studied. The hybrid materials possess good stability and excellent luminescent property. The results provide useful path to obtain luminescent hybrids for further practical application.
