Novel chalcone scaffolds of benzothiophene as an efficient real time hydrazine sensor: Synthesis and single crystal XRD studies

A selective bis‐thiophene chalcone‐based spectrofluorimetric sensor for Fe3+

“…Due to C-H stretching, IR spectra displayed a distinctive band at 3077 cm À1 , which was theoretically estimated to be 3,113 cm À1 . The theoretical spectra predicted that the aromatic C=C bonds would appear at 1576 cm À1 ; however, they were found around 1,578 cm À1 [75,76]. The compound BTC's UV-visible spectra were examined between 200 and 800 nm, and the TD-DFT method was used to theoretically determine the compound's electronic spectrum.…”
