Three 3D lanthanide anionic metal-organic frameworks {K(5)[Ln(5)(IDC)(4)(ox)(4)]}(n) x (20H(2)O)(n) with 1D channels were synthesized under hydrothermal conditions [Ln = Gd (1), Tb (2), and Dy (3)]. The K(+) ions within the 1D channel are easily exchanged with various cations. The emission intensities of Tb(III) in 2 increased significantly upon the addition of Ca(2+) ions, while the introduction of other metal ions caused the intensities to be either unchanged or weakened.
在水热条件下合成了三种具有一维孔道的三维镧系阴离子金属有机框架{K(5)[Ln(5)(IDC)(4)(ox)(4)]}(n) x (20H(2)O)(n) [Ln = Gd (1)、Tb (2) 和 Dy (3)]。一维孔道内的K(+)离子易于与各种阳离子发生交换。加入Ca(2+)离子后，2中Tb(III)的发射强度显著增加，而引入其他金属离子则导致强度不变或减弱。
