Synthesis and photophysical investigation of novel imidazole derivative an efficient multimodal chemosensor for Cu(II) and fluoride ions

Aminophenylbenzimidazole derivative of theonyl trifluoro acetone has been designed, synthesized and characterized to sense Cu(II) and fluoride ions. The probe showed very selective colorimetric and ratiometric fluorescence changes with copper(II), turn-on fluorescence behavior with fluoride ions. ESI-MS analysis and jobs plots analysis provided the information about the interaction mode between Cu(II) and the probe. Density functional theory...
