| 摘 要： | Novel soft materials,Eu(III)-containing complex dissolved in C8mim]X](X=Cl-,PF6-and Tf2N-) ionic liquids,were synthesized.FT-IR and elementary analysis of complex proved that the molecular formula is C8mim]Eu(TTA)4].The complex and ionic liquids had highthermal stability according to TGA.The photoluminescence spectra showed that the C8mim]Eu(TTA)4] exhibited typical red emission deriving from 5D0-7F2 transition.After dissolving the complex in C8mim]X](X=Cl-,PF6-and Tf2N-) ionic liquids,the luminescence intensitydecreased in the following order:C8mim]Tf2N]≈C8mim]PF6 ]>C8mim]Cl].This was because Tf2N-and PF6-anions had larger molecularvolume and weaker coordination ability than Cl-.
