Microwave-Assisted One-Pot Synthesis of Indole-Based Fluorescent Probe for Sensitive Detection of Copper (II).

In this study, a rapid, inexpensive and convenient microwave assisted synthesis of indole-3-propionic acid-bisphenol A diglycidyl ether (IPA-SR3) fluorescent probe was developed. This fluorescent probe has the dual illumination characteristics of photoinduced electron transfer and aggregation-induced emission for the specific detection of Cu ion in water. The wavelength-dependent photoluminescence behavior of the aggregated IPA-SR3 was highly selective (Ksv = 1.
