Task-specific ionic liquids can be applied to many fields by grafting various functional groups to the cations or anions part. Terpyridine functional group has strong σ-electron-donating ability to form complexes with various metal ions, lanthanide ions are attractive luminescent properties because of their special electronic structure. In this paper, we synthesized terpyridine functionalized poly(ionic liquid) and several binary lanthanide complexes, terpyridine can form luminescent materials upon complexing with lanthanide complexes. Ionic liquid monomer Terpy-Vim[Br] and the poly (ionic liquid) were successfully synthesized by us, which were characterized by NMR. Binary lanthanide complexes Eu(TTA)3·2H2O,Nd(TTA)3·2H2O,Er(TTA)3·2H2O were synthesized by complexing 2-thenoyltrifluoroacet(TTA) with Eu3+, Nd3+,Er3+ ions . Novel luminescent materials were synthesized by coordi
