ABSTRACT
Chemical sensing of specic metal ions and anions is an important event in living organisms [1,2]. It is thus reasonable to mimic biological systems when articial chemical sensors are designed. Biological systems are composed of assembled macromolecules with well-dened molecular weights and shape persistency, and the recognition events of guest molecules and ions are often governed by unique environments. For example, control of chiral molecular recognition has been the focus of supramolecular and macromolecular chemistries. To realize an articial chiral molecular recognition, one-handed helical macromolecules and chiral molecular assemblies have been developed as host platforms, and their recognition behaviors toward enantiomeric guests suggested that an amplied chiral recognition can be achieved by supramolecular assemblies [3-6].
