Design, synthesis and evaluate of imidazole, triazine and metastable oxazolone derivatives as chemosensor for detecting metals

In the current work, a novel series of substituted imidazole, triazine and metastable Oxazolone derivatives were synthesized. The performance of 4-arylideneoxazol-5(4H)-one (2a-c) towards amoniuma acetate, hydrazine hydrate, phenyhydrazine and primary amines has been discussed. DFT bases and calculations of HUMO, LUMO were used to predict the ability of binding between synthesized compound and cations. All the synthesized compounds were assessed as chemosensors for detection metals ions. Colorimetric investigation confirmed and showed highselectivity and specificity of compounds 5b and 5c to detect cobalt ion, and copper ion respectively, so compounds 5b and 5c can be directed as a chemosensor for optical detection of Co(2+)and Cu2+ respectively. On the other hand, new organic chemosensor were established by, IR, H-1 NMR, C-13 NMR ms spectroscopy and elemental analysis.(c) 2022 The Author(s).

Automated summary

In this study, a series of novel compounds were synthesized and their performance towards certain compounds was investigated. The results showed that two compounds exhibited high selectivity and specificity for detecting specific metal ions. Additionally, a new organic chemosensor was established using multiple analysis methods.
