| 摘要: 使用碘化亚铜、预先合成的硼咪唑配体和季铵盐制备得到了2例铜碘簇基硼咪唑框架(boron imidazolate frameworks，BIFs)，并对其结构与性能进行了表征。X射线单晶衍射结果显示，[N(C4H9)4]{Cu6I6[BH(im)3]Cu[BH(im)3]}·0.5CH3OH (BIF-155，im=imidazolate)是以四连接的Cu6I6簇、单核Cu原子和三连接的硼咪唑配体BH (im)3-作为节点交替连接形成的(3，4)-连接的二维层状网络，[N(C4H9)4]{Cu3I3[BH(im)3]}(BIF-156)则是以Cu3I3簇和BH(im)3-硼咪唑配体连接得到的3-连接的fes拓扑的二维层状网络。2种化合物对应的晶体均具有良好的结晶性。在紫外灯照射下，二者展示出不同的荧光性质，即BIF-155发射红光，BIF-156发射黄光。 |

| Abstract: Two examples of copper-iodine cluster-based boron imidazolate framework (BIFs) were obtained using cuprous iodide, pre-synthesized boron imidazolate ligands, and quaternary ammonium salts. Their structures and properties were characterized. X-ray single crystal diffraction results show that [N(C4H9)4]{Cu6I6[BH(im)3]Cu[BH(im)3]}·0.5CH3OH (BIF-155，im=imidazolate) is a (3, 4) - connected two- dimensional layer network formed by alternately connecting four-connected Cu6I6 clusters, single core Cu atoms and triple - connected boron imidazolate ligands BH(im)3-. [N(C4H9)4]{Cu3I3[BH(im)3]}(BIF-156) is a 3-connected two-dimensional layer network with fes topology obtained by connecting Cu3I3 clusters and BH(im)3- boronazole ligands. The corresponding crystals of the two compounds had good crystallinity. Under ultraviolet lamp illumination, the two showed different fluorescence properties, that is, BIF-155 emited red light and BIF-156 emited yellow light. |
