Synthesis and Computational Study of an Optical Fluorescent Sensor for Selective Detection of Ni²⁺ Ions.

ABSTRACT: The presence of an abnormal amount of Ni²⁺ in the human body causes various health issues. Therefore, this work aimed to synthesize the curcumin-based fluorescence-on sensor P [2,6-bis((E)-4-chlorobenzylidene)-cyclohexan-1-one] that was capable of selectively responding to Ni²⁺ ions in aqueous solution. The structure of P was confirmed by ¹H NMR and Fourier transform infrared (FTIR) spectroscopy. The Ni²⁺ ion sensing was based on the fluorescence enhancement of the fluorophore (P) in neutral aqueous medium. The response of the P-based sensor was highly selective toward Ni²⁺ ions, whereas the possible interferences from other metal cations were negligible. P ha
