Luminescent Ionogels Based On Carboxylate-functionalized Ionic Liquids

The carboxylate-functionalized ionic liquids (TSILs) are a kind of green solvent andefficient catalyst.They have been a hotpot research area in catalysis synthesis and materialscience and the use of them are beoming more and more widespread recently.Two types of novelluminous ionogel have been synthesized basing on carboxylic acid task-spectific ionic liquid inthis thesis,then a series of research on the propertys of the materials have been done.(1) Bright red light ionogels were prepared by ionic liquids、Eu3+、tta ligand and methylmethacrylate(MMA); Bright green light ionogels have also been obtained from ionic liquids、Tb3+、salicylic acid methyl and methacrylate(MMA).Flexiblity of ionogels can be changed withthe proportion between ionic liquids and MMA.The affection of MMA on the luminescentbehavior of Eu3+or Tb3+ions in the ILs were also discussed.(2)We described the synthesis of terpyridyl–functionalized ILs with linear alkyl chain ofvarious length.It proved that products were very purity through NMR-1H spectrum.Terpyridyl of[Tf2N] anion has been synthetized displacing the bromine. Lanthanide complexes composed ofcarboxylic acid ionic liquid, terpyridine and Eu3+ions were obtained and the resulting complexeswere fully characterized by TGA, FT-IR and photoluminescence spectroscopy.
