稀土与β-二酮及2-（2-吡啶）苯并咪唑三元配合物的研究

As useful fluorescent reagent, rare earth complexes with β-diketones have been　extensively studied. Four new rare earth (La, Eu) ternary complexes with　β-diketones, (benzoylacetone (Hbza), 2-thenoyltrifluoroacetone, (HTTA)) and organic base (2-(2-pyridyl) benzimidazole, (Hpbi)) have been synthesized and characterized by elemental analysis, IR, NMR. The general formulae of these complexes are ［Ln(bza)₃(Hpbi)］ and［Ln(TTA)₃(Hpbi)］. The effects of coordinated base on UV, especially on fluorescent properties of the complexes were discussed. The results showed that the dehydro-Hpbi, pbi^{－, strongly enhances the fluorescence of the complexes.}     

簇合物裂解法合成二硫纶化合物

以[Me₄N]₂[M₄(SPh)₁₀]和[Me₄N]₄[S₄M₁₀(SPh)₁₆](M=Cd,Zn)为前驱体,采用簇合物裂解法合成了配合物(Bu₄N)₂[Cd(mnt)₂]、(Bu₄N)₂[M(dmit)₂](M=Cd,Zn)以及双核配合物(Me₄N)₂[Zn₂(Sph)₂·(S₂TTF(SCH₂)₂)₂].运用PM3计算方法得到了各种二硫纶盐配体中硫负离子的静电荷大小关系:mnt^2->SPh^->dmit^2->[(MeS)₂TTFS₂]^2-≈[(CH₂S)₂TTFS₂]^2-.在理论计算及实验结果的基础上,探讨了配体上硫负离子的静电荷大小与反应产物间的关系.
