Abstrakt: The chalcone compound DHPO was synthesized through a chemical reaction between 1-(2-hydroxyphenyl)-ethanone and 3,4-dimethoxy benzaldehyde under ultrasound irradiation. The interaction between the DHPO compound and several metal ions was studied using fluorescence behavior, revealing that the chalcone function as a "turn on and turn off" switch fluorescent sensor, for selectively and sensitively detecting Fe 3+ ions. The process of fluorescence quenching and complexation of DHPO with Fe 3+ ion was further studied using methods such as Benesi-Hildebrand, Stern-Volmer plot, and job plot.
