采用水热法合成了新的一维链状锌的配位聚合物[Zn(tpa)(tripy)]n.nH2O(tpa=对苯二甲酸,tripy=4′-(4-甲氧基苯基)-2,2′∶6′,2″-三联吡啶),通过红外光谱和元素分析对该配位聚合物进行了结构表征,用X射线单晶衍射测定了晶体结构。结果表明,该配位聚合物属单斜晶系,P21/c空间群,a=0.855 0(2)nm,b=2.825 0(6)nm,c=1.096 0(2)nm,β=107.14(3)°,V=2.529 7(9)nm3,Z=4,Dc=1.541 g/cm3,Mr=586.88,F(000)=1 208。最终偏离因子R1=0.100 6,ωR2=0.264 8。该化合物中Zn原子和2个对苯二甲酸酸根中的2个O原子和1个三联吡啶中的3个N原子配位。相对于配体,该配位聚合物表现出明显增强的荧光发射性质。
Hydrothermal synthesis of a new one-dimensional chain zinc coordination polymer [Zn (tpa) (tripy)] n.nH2O (tpa = terephthalic acid, tripy = 4’- ) -2,2 ’: 6’, 2 "- terpyridine), the structure of the coordination polymer was characterized by IR and elemental analysis and the crystal structure was determined by X-ray single crystal diffraction.The results show that the The coordination polymer belongs to the monoclinic system with a = 0.855 0 (2) nm, b = 2.825 0 (6) nm, c = 1.096 0 , V = 2.529 7 (9) nm3, Z = 4, Dc = 1.541 g / cm3, Mr = 586.88 and F (000) = 1 208. The final deviation factor R1 = 0.1006 and ωR2 = 0.264 8. The Zn The atoms are coordinated with two O atoms in two terephthalates and three N atoms in one terpyridine, which exhibit significantly enhanced fluorescence emission properties relative to the ligands.
