| 摘要: 合成了具有锥形构象的含氟功能基团的杯芳烃衍生物1~3，并用单晶X射线衍射和核磁共振证实了其锥形构象。在混合溶剂中，研究了杯芳烃衍生物1~3对多种金属离子的识别行为。测试了化合物1~3的紫外-可见吸收光谱和荧光发射光谱，结果显示铜离子对化合物1~3具有明显的荧光猝灭特性，而其它金属离子（如Na'，K'，Cs'，Mg2'，Ca2'，Ba2'，Fe3'，Cd2'，Mn2'，Co2'，Ni2'，Zn2'）对化合物1~3的紫外-可见吸收光谱和荧光发射强度无显著的影响，表明化合物1~3对铜离子的识别具有高选择性。 | ||||||||||

| Abstract: The fluorine derivatives of calix[4]arene, C64H52F12O4 (1), C60H52F4O4 (2), C68H48F24O4 (3), were synthesized, and their cone conformations were proved by single crystal X-ray diffraction and 1H NMR spectroscopy. Their recognition behaviors were evaluated towards a variety of metal ions in mixed solvent. The UV-Vis absorption and fluorescence spectroscopy were measured and confirmed that copper ions resulted in fluorescence quenching of compounds 1~3, while other ions such as Na', K', Cs', Mg2', Ca2', Ba2', Fe3', Cd2', Mn2', Co2', Ni2', Zn2' exerted hardly significant impact on the UV-Vis absorption and fluorescence intensity of 1~3, exhibiting high selectivity of compounds 1~3 to copper ions. | ||||||||||
