Design, synthesis and characterization of a highly luminescent Eu-complex monomer featuring thenoyltrifluoroacetone and 5-acryloxyethoxymethyl-8-hydroxyquinoline

►iWe designed and synthesized a highly luminescent Eu-complex monomer. ► Quantum yield and lifetime of the complex are 30.6% and 389 μs, respectively. ► Excellent luminescence of the complex made it an excellent luminescent monomer.
