synthesized by incorporating the imidazolium and 1,8-naphthalimide dye moieties into a preorganized tripodal receptor. The novel sensor displays high selectivity for Cu(ClO4)2 and Cu(NO3)2 over a wide range of tested metal ions, anions, and Cu2+ salt ion pairs. Upon adding Cu(ClO4)2 or Cu(NO3)2 to the probe solution, the fluorescence emission was significantly turned on concomitant with a blue shift

金属离子,阴离子和Cu 2+盐离子对上均显示出对Cu(ClO 4)2和Cu(NO 3)2的高选择性。向探针溶液中添加Cu(ClO 4)2或Cu(NO 3)2时,由于阴离子引起的构象变化和配位效应,荧光发射显着打开,同时发射能量发生蓝移。通过进一步结合模型研究1H核磁共振波谱和质谱表明,该受体与Cu(ClO 4)2或Cu(NO 3)2形成了1 :1的客体复合物。
