摘要
Novel soft materials, Eu（Ⅲ）-containing complex dissolved in [C8mim][X] （X=Cl-, PF-6 and Tf2N） ionic liquids, were synthesized. FT-IR and elementary analysis of complex proved that the molecular formula is [Csmim] [Eu（TTA）4]. The complex and ionic liquids had high thermal stability according to TGA. The photoluminescence spectra showed that the [Csmim][Eu（TTA）4] exhibited typical red emission de- riving from 5Do-7F2 transition. After dissolving the complex in [Csmim][X] （X=C1, PF6- and Tf2N-） ionic liquids, the luminescence intensity decreased in the following order： [Csmim][Tf2N]=[Csmim][PF6 ]〉[Csmim][C1]. This was because Tf2N- and PF6 anions had larger molecular volume and weaker coordination ability than Cl.
