摘要
以1,3-二咪唑丙烷(bbi),对苯二甲酸(tpa)和Zn(NO3)2·6H2O为原料,经水热法合成了具有二重穿插的二维锌(Ⅱ)配位聚合物{[Zn(bbi)(tpa)]n(1)},其结构和性能经IR,元素分析,XRD,TG和FL表征。l属正交晶系,Pbca空间群,晶胞参数Ⅱ=1.06726(4)nm,b=1.58618(6)nm,c=2.02582(5)nm,Dc=1.572g·cm^-3,V=3.429nm^3,Z=8,R,=0.0586,wR2=0.1461。1中每个Zn(Ⅱ)作为一个四连接的节点,通过tpa和bbj桥联连接形成了二维(4,4)网格结构,相邻的两个二维(4,4)网格层通过相互穿插,形成一种有趣的二重穿插二维构型。1的初始分解温度为300℃;室温固体荧光测定结果表明:在330nm波长激发下,1的最大发射波长位于421nm。
The two dimensional coordination polymer, [ Zn (bbi) (tpa) ], (1), was synthesized by co- ordination reaction of 1,3-bis(imidazole) propane( bbi), terephthalic acid(tpa) and znic nitrate hexa- hydrate by hydrothermal method. The structure and performances were characterized by IR, elemental analysis, XRD, TG and FL. 1 belongs to orthorhombic system, space group Pbca with a = 1. 067 26(4) nm, b=1.586 18(6) nm, c=2.025 82(5) nm, Dc=1.572 g·cm^-3, V=3.429 nm3, Z=8, R1 = 0.058 6, wR2 =0. 146 1. The bbi and tpa ligands links Zn cation to form a 2D rectangular(4,4) grid layer along. Then a pair of identical 2D single nets is interlocked with each other to form a 2-fold parallel interpenetrated 2D/2D architecture. Initial decomposition temperature of 1 was 300 ℃. An excitation band at 330 nm, intense emissions are observed at 421 nm for 1 in the solid state at room temperature.
