摘要: 本文在无水乙醇中制备了铕的四元、三元和二元系列配合物,当配体Phen和TTA共存时,协同发光效应使得Eu(Phen)2(TTA)2的荧光最强。在铕配合物和纳米级介孔分子筛MCM-41或(CH3)3Si-MCM-41组成的超分子发光体系中,主体分子筛的疏水孔道环境有利于客体铕配合物的发光,说明主客体之间弱的相互作用会对复合的超分子纳米发光材料的荧光性质产生影响。

Abstract: Europium complexes, Eu(Phen)2(TTA)(D-py), Eu(Phen)x (TTA)y (x=3,2,1;y=1,2,3), Eu(Phen)4 and Eu(TTA)4 were prepared in EtOH solutions. The fluorescent intensity of Eu(Phen)2 (TTA)2 in EtOH is the strongest due to the synergy effect of Phen and TTA.Supramole-cular functional NSM (nanostructured materials) that the guest complexes were encapsulated in the non-polar channels of mesoporous molecular sieve (CH3)3Si-MCM-41 are stronger than supramolecular functional NSM that the guest complexes were encapsulated in the polar channels of mesoporous molecular sieve MCM-41 in fluorescence. The experimental result indicates that the interactions between host and guest can influence the fluorescent property of NSM.
Keywords: MCM-41  (CH3)3Si-MCM-41  functional NSM of supramolecule  fluorescence
