A series of 1D chain assembled from squarate and 2,2'-bipyridine ligands:syntheses,structures,third-order nonlinear optical and fluorescent properties

使用方酸(H_2C_4O_4)和2,2’-联吡啶(C_(10)H_8N_2)为配体合成了3种中性一维配位聚合物[M(C_4O_4)(C_(10)H_8N_2)(H_2O)_2]·2H_2O(M=Zn_(2+)Cd_(2+) or Cu_(2+)).所有的配位聚合物通过元素分析、红外光谱、X射线单晶衍射、热重分析和紫外-可见光谱等测试进行了表征.在这些配位聚合物中,金属中心离子和参与配位的两个吡啶环氮原子、两个方酸氧原子和两个配位水氧原子共同构成了六配位的伪八面体结构.其中拥有d10电子结构的金属离子的配位聚合物在荧光发射光谱中的374.5nm和464.5nm处有很强的荧光强度.同时通过Z扫描技术研究了铜离子配位聚合物的三阶非线性光学性质.

Three neutral one-dimensional coordination polymer 1,2 and 3[M（C_4O_4）（C_（10）H_8N_2）（H_2O）_2]·2H_2O（M=Zn^（2＋）Cu^（2＋） or Cd^（2＋））have been synthesized by H_2C_4O_4 and 2,2＇-bipyridine co-ligands.All complexes have been characterized by elemental analysis,IR,single crystal X-ray diffraction,thermogravimetric analysis（TGA）and UV-vis spectra.All metal ions in the polymers have six coordinate pseudo octahedral structures with two pyridyl nitrogen atoms,two squarate oxygen atoms and two waters.The complexes with d10 metals exhibit a strong emission band with the maximum intensity at 374.5 nm and 464.5 nm.The third-order nonlinear optical（NLO）property of the Cu^（2＋） complex was also investigated by single beam Z-scan techniques.
