摘　　要：通过水热法合成2种金属有机骨架化合物,X-射线衍射、红外、热重等分析表明它们具有相同结构、较高的热稳定性和绝对纯度。研究了Cd-MOF对一系列溶剂小分子的荧光传感。结果表明,THF对Cd-MOF的荧光发射显示出明显的荧光增强效应,而苯甲醇对Cd-MOF的荧光发射显示出明显的荧光淬灭效应。这种主-客体相互作用改变荧光强度的现象对于检测环境中的有害分子具有重要意义。In this paper,two kinds of metal-organic framework(MOFs)were synthesized by hydrothermal method.X-ray diffraction,infrared and thermogravimetric analysis showed that they have the same structure,high thermal stability and absolute purity.The fluorescence sensing of Cd-MOF to a series of solvent small molecules was studied.The results revealed that the emission of THF to Cd-MOF showed obvious turn-on effect,while the emission of benzyl alcohol to Cd-MOF revealed obvious turn-off effect.This phenomenon of host-guest interaction changing fluorescence intensity is of great significance for the detection of harmful molecules in the environment.
