The fluorescent assemblies having specific binding sites act as selective sensory ensembles for the detection of various biologically important metal ions and anions such as Na+, K+, Mg2+, Ca2+, Fe2+, Zn2+,SO42–,NO3C2O42– and CH3COO– ions. In some cases these fluorescent aggregates further undergo metal ion or anion induced aggregation or disaggregation in mixed aqueous media which results in modulation of their self-assembled architectures. The present review focuses on the summarization of different findings highlighting the concepts of AIEE for the preparation of fluorescent materials and their application for the development of ion coordinated self-assembled architectures. |
