Abstract

Abstract : A novel fluorescent probe for the detection of multi metal ions was designed and synthesized based on the fluorophores of biphenyl and rhodamine. Abstract : At present, the design of multi ion sensing receptors is a new area of research due to their potential application in the recognition of analytes. Herein, a novel fluorescent probe for the detection of multi metal ions was designed and synthesized based on the fluorophores of biphenyl and rhodamine. Probe1 exhibits multiple fluorescence responses to various metal ions (Zn 2+, Al 3+, Cr 3+ and Fe 3+ ) and is accompanied by different optical signal outputs. Moreover, the interference between the target ions can also be effectively solved by the introduction of probe2 and the addition of the corresponding anions. Probe1 was also successfully used to detect trace metal ions in real water samples and silicone plate test strips were prepared for the rapid qualitative detection of target metal ions. In addition, in order to better understand the multiple response mechanism of probe1, geometry optimizations and electronic calculations were carried out at the B3LYP/6-31G*/LANL2DZ level of theory. And harmonic vibrational frequency calculations were also carried out to ensure that all optimized structures were at energy minima on the potential energy surface.
