Abstract

In this work, a novel fluorescent chemosensor 3-(2-(2-(4-(diphenylamino)phenyl)-4,5-diphenyl-1H-imidazol-1-yl)thiazol-4-yl)-2H-chromen-2-one (TCCM) was effectively synthesized and characterized through NMR and Mass spectrum. An approach towards the recognition of Cu²⁺ and Co²⁺ ions using a turn-off fluorescence technique was developed. The chemosensor TCCM also exhibited colorimetric and fluorometric sensing behaviour with a visible colorimetric response to trifluoroacetic acid (TFA). Upon the addition of TFA to TCCM, a new peak formation at 500 nm in the absorption spectra along with the visible colour change from colourless to brown. In addition, it exhibits high selectivity towards Cu²⁺ and Co²⁺ ions with a limit of detection of 4.2 and 3.9 μM, respectively. It was discovered that the sensor was quite selective for Cu²⁺ and Co²⁺ ions that had a lot of competing ions. Further, the studies were supported by DFT analysis and NBO studies.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
