| 中文摘要: |
| 通过优化后的甲醇蒸汽扩散法合成了一种新型基于β-环糊精有机分子和碱金属(K＋)配位的金属有机框架(β-CD-MOF1),并进行了扫描电镜(SEM)、红外光谱(IR)、粉末衍射(XRD)、热重(TG)表征;单晶X射线衍射分析表明β-CD-MOF1具有碗状孔隙和“8”型双通道三维构型,属于单斜晶系,P21空间群,分子式为C42H72O40K,a＝15.233 0(11)×10－10 m,b＝10.600 4(8)×10－10 m,c＝20.301 4(14)×10－10 m,α＝90°,β＝108.739°(2),γ＝90°。β-CD-MOF1在保留了β-环糊精的空腔结构的基础上,由K—O键的配位连接形成了有序排列的三维多孔框架。β-CD-MOF1有望成为一种新型的多功能绿色晶体材料。 |
| 英文摘要: |
| A new metal organic framework (β-CD-MOF1) based on the coordination of β-Cyclodextrin organic molecules and alkaline metal (K＋) was synthesized by optimized methanol vapor diffusion method and characterized by Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (IR), Powder diffraction (XRD), Thermogravimetric (TG). X-ray single crystal diffraction analysis shows that the three-dimensional configuration of β-CD-MOF1 have bowl pores and “8” type of dual-channel, which belong to monoclinic system and P21 space group. The formula is C42H72O40K, a＝15.233 0(11)×10－10 m, b＝10.600 4(8)×10－10 m, c＝20.301 4(14)×10－10 m, α＝90°, β＝108.739° (2), γ＝90°. On the basis of retaining the cavity structure of β-cyclodextrin, the ordered three-dimensional porous frame is formed by the coordination connection of the K—O bond. The β-CD-MOF1 is expected to become a new multifunctional green crystal material. |
