摘要: Ionic liquids as novel spectroscopic solvents for Eu(III)-containing complex
研究领域[WOS]: Chemistry
英文摘要: Novel soft materials, Eu(III)-containing complex dissolved in [C(8)mim][X] (X=Cl-, PF6- and Tf2N-) ionic liquids, were synthesized. FT-IR and elementary analysis of complex proved that the molecular formula is [C(8)mim][Eu(TTA)(4)]. The complex and ionic liquids had high thermal stability according to TGA. The photoluminescence spectra showed that the [C8mim][Eu(TTA) 4] exhibited typical red emission deriving from D-5(0)-F-7(2) transition. After dissolving the complex in [C(8)mim][X] (X=Cl-, PF6- and Tf2N-) ionic liquids, the luminescence intensity decreased in the following order: [C(8)mim][Tf2N]approximate to[C(8)mim][PF6]>[C(8)mim][Cl]. This was because Tf2N- and PF6- anions had larger molecular volume and weaker coordination ability than Cl-.
