五个新的稀土与新的柔性三脚架水杨酸配体(H(3)L)，2，2‘-(2-((2-carboxyphenoxy)methyl)-2-(4-methylphenylsulfonamido)propane-1，3-diyl)bis(oxy)dibenzoic酸，式[La(2)L(2)(DMF)(4)]·4DMF·4EtOH·2H(2)O(1)，[Eu(2)L(2)(DMF)(4)]·2DMF(2)，合成了{[GdL(Dmf)(H(2)O)(2)]·dmf}(∞)(3)，{[tbl(Dmf)(H(2)O)(2)]·dmf}(∞)(4)和{[YL(Dmf)(H(2)O)(2)]·dmf}(∞)(5)(dmf=N，N-二甲基甲酰胺)。单晶X-射线衍射分析表明，配合物1和2为笼状同双核物种，而3-5为螺旋一维配位聚合物。所有这些配合物都通过氢键或π-π相互作用进一步连接，形成了三维超分子结构。研究了Eu和Tb配合物在室温固态下的光物理性质。
Five new rare earth complexes with a new flexible tripodal salicylic ligand (H(3)L), 2,2'-(2-((2-carboxyphenoxy)methyl)-2-(4-methylphenylsulfonamido)propane-1,3-diyl)bis(oxy)dibenzoic acid, of formulae [La(2)L(2)(DMF)(4)]·4DMF·4EtOH·2H(2)O (1), [Eu(2)L(2)(DMF)(4)]·2DMF (2), {[GdL(DMF)(H(2)O)(2)]·DMF}(∞) (3), {[TbL(DMF)(H(2)O)(2)]·DMF}(∞) (4) and {[YL(DMF)(H(2)O)(2)]·DMF}(∞) (5) (DMF = N,N-dimethylformamide) have been prepared. The single-crystal X-ray diffraction analysis revealed that complexes 1 and 2 present a cage-like homodinuclear species, while 3-5 show a helical one-dimensional coordination polymer. All these complexes are further connected by hydrogen bonds or π-π interactions, resulting in 3D supramolecular structures. The photophysical properties of the Eu and Tb complexes are investigated in the solid state at room temperature.
