摘要

The development of novel strategies to achieve efficient detection of ions in water is an intriguing challenge. Moreover, due to its high hydration enthalpy, the detection of F ~(?) in water is a very difficult task. Herein, we report a novel and efficient method for highly selective detection of ions in water. This novel approach can be illustrated as follows. First, water soluble cationic pillar[5]arene ( P5 ) and aromatic acid derivatives ( N1 ) that were self-assembled in water formed supramolecular sensors ( P5N1 ). Then, competitive coordination was rationally introduced into these supramolecular sensors by adding metal ions (such as Fe ~(3+) ) to form new supramolecular sensors ( P5N1Fe ). Interestingly, the supramolecular sensor P5N1Fe showed a high selectivity for F ~(?) in water solution. Therefore, this suggests that this method is a novel and facile way to design sensors for the efficient sensing of ions in water.
