【摘要】 镧系配合物在配位化学和镧系发光材料领域一直备受青睐。近年来,具有发光效率高及稳定性好等优点的离子液型镧系配合物引起研究者的广泛关注。为开发新型镧系发光材料、拓宽离子液型镧系发光配合物的应用领域,将离子液型镧系配合物负载于无机基质组装成无机-有机杂化材料成为研究热点。本论文以凹凸棒石黏土为基质,3-氯丙基-三乙氧基硅烷为偶联剂,通过加入1-甲基咪唑形成离子液型的凹凸棒,进而通过离子交换反应引入β-二酮镧系配合物,组装出类似于[C₄mim][Ln（TTA）₄]的新型镧系配合物@凹凸棒的离子液型杂化材料,进一步探讨主客体相互作用对杂化材料光物理性质的影响,为实现器件化应用提供理论依据。更多还原

【Abstract】 Interest in lanthanide complexes has grown considerably in coordination chemistry and lanthanide luminescent materials during the last decade.The combination of ionic liquids with lanthanide complexes have been focused on the recent publications,which exhibit high-luminescence quantum yields and enhanced photostabilities.In order to develop novel lanthanide materials and widen the filed of applications,doping ionic liquid-type lanthanide complexes into matrices has attract a great amount of attentions. Herein we discuss the preparation and luminescence of hybrids which have been assembled by the ionic liquid-type lanthanide complexes attached to attapulgite（atta）.First,atta was anchored by l-propyl-3-methylimidazolium groups.Then we could prepare an immobilized analogue of the complex [C₄mim][Ln（TTA）₄]by an ion exchange route.The results of this work would have potential significance for the design and assembly of the luminescent lanthanide materials for high performance luminescence application.更多还原
