以1∶2物质的量之比的Ag2O和Hpyca(异烟酸)为原料,在水热条件下得到了一个新颖的三维配位聚合物[Ag(pyca)]n·nH2O(1)。单晶X-射线结构分析表明,1晶体属于单斜晶系,P21/c空间群,1的空间堆积在沿a轴方向形成了大小为0.66nm×0.84nm的方形孔洞。1的固体室温荧光测试结果表明,在波长为469nm的光激发下于524nm处出现强烈的荧光发射。
A new three - dimensional coordination polymer [Ag (pyca)] n · nH2O (1) was obtained under hydrothermal conditions using Ag2O and Hpyca (isonicotinic acid) in the ratio of 1: 2. Single crystal X-ray structure analysis showed that crystal 1 belongs to the monoclinic space group P21 / c and space accumulation of 1 forms a square hole of 0.66 nm × 0.84 nm in size along the a-axis. 1 solid room temperature fluorescence test results show that at a wavelength of 469nm light excitation at 524nm strong fluorescence emission occurs.
