一系列有机-无机杂化聚氧乙烯醚衍生物{[Cu（en）（2）]（1.5）[Cu（en）（2，2'-bipy）（H2O）（n）]Ce[（α-PW 11 O39）（2）]}（6-）[（Ln，n）=（Ce（III），0）对于1，（Pr-III，1）for 2）]，{[Cu（en）（2）]（2）（H2O）[Cu（en）（2，2'-bipy）]Ln[（α-HPW11O39）（2）]}（4-）[Ln = Gd-III（3），Tb-III（4），Er-III（5）]和{[Cu（en）（2）]（1.5）[Cu（en）（2，2'-bipy）]Nd[（alpha-H5 PW 11 O39）（2）]}（3-）为6在水热条件下成功合成了（2，2 '-bipy =2，2'-bipyridine，en =乙二胺），并通过元素分析、电感耦合等离子体（ICP）分析、X射线粉末衍射（XRPD）、IR光谱、UV光谱、电子顺磁共振（EPR）光谱、热重（TG）分析和单晶X射线衍射。化合物1-6的共同特征是它们都是以Ln（alpha-PW 11 O 39）（2）]（11-）多氧阴离子为基本结构单元，以铜配位阳离子为桥。1和2显示了一维锯齿链，3-5显示了前所未有的由[Ln（alpha-PW 11 O 39）2]（11-）多氧阴离子和[Cu（en）（2）]（2+）和[Cu（en）（2，21-bpy）]（2+）阳离子构建的二维结构，而6显示了罕见的具有（4（6）.6（4））拓扑结构的三维骨架。如所预期的，1-6含有两种类型的有机配体。此外，还研究了罗丹明B（RhB）在500 W汞灯照射下，在1、2、3、4、5、6等5种化合物存在下的荧光性质。研究了4的光致发光性质。
A series of organic-inorganic hybrid polyoxometalate derivatives {[Cu(en)(2)](1.5)[Cu(en)(2,2'-bipy)(H2O)(n)]Ce[(alpha-PW11O39)(2)]}(6-) [(Ln, n) = (ce(III), 0) for 1, (Pr-III, 1) for 2)], {[Cu(en)(2)](2)(H2O)[Cu(en)(2,2'-bipy)]Ln[(alpha-HPW11O39)(2)]}(4-)[Ln = Gd-III for 3, Tb-III for 4, Er-III for 5] and {[Cu(en)(2)](1.5)[Cu(en)(2,2'-bipy)]Nd[(alpha-H5PW11O39)(2)]}(3-) for 6 (2,2'-bipy =2, 2'-bipyridine and en = ethylenediamine) have been successfully synthesized under hydrothermal conditions and further characterized by elemental analyses, inductively coupled plasma (ICP) analyses, X-ray powder diffraction (XRPD), IR spectra, UV spectra, electron paramagnetic resonance (EPR) spectra, thermogravimetric (TG) analyses, and single-crystal X-ray diffraction. The common features of 1-6 are that they all consist of sandwich-type [Ln(alpha-PW11O39)(2)](11-) polyoxoanions as the fundamental building blocks and copper coordination cations as bridges. 1 and 2 show the 1-D zigzag chains, and 3-5 exhibit the unprecedented 2-D structures built by [Ln(alpha-PW11O39)2](11-) polyoxoanions and [Cu(en)(2)](2+) and [Cu(en)(2,21-bpy)](2+) cations, whereas 6 displays the scarce 3-D framework with a (4(6).6(4)) topology. As expected, 1-6 contain two types of organic ligands. Furthermore, the photocatalysis properties of rhodamine-B (RhB) upon a 500W Hg lamp irradiation in the presence of 1, 2, 3, 4, 5, or 6 have been examined. The photoluminescence property of 4 has been investigated.
