molecule (L2) allows selective recognition of Fe3 + colorimetrically in CH3CN. The structure of L2 is confirmed from single crystal X-ray diffraction analysis. The probe displays two different visible bands at 541 nm and 715 nm in the presence of Fe3 +, associated with two different colors, viz. green and pink-violet allowing determination of unknown Fe3 + concentration. Interestingly, removal of 2-picolyl

Abstract Two novel Schiff-base fluorescentprobes bearing different substituents were synthesized by the reaction of indole derivatives with 4-aminoantipyrine. The fluorescent behavior toward Cu2+ was studied by analyzing ultraviolet–visible (UV–Vis) absorption spectra and fluorescence spectroscopy results, which demonstrated that compound 2 containing a methoxy moiety exhibited improved selectivity

Their chemical structures were confirmed using spectroscopic tools including IR, 1H NMR, 13C NMR mass spectroscopy and elemental analyses. The results showed no significant cytotoxic activity on either cancer or normal human cells. Anti-inflammatory activity for all target compounds was evaluated in vitro. Compounds 5a–h were found to have better anti-inflammatory activity than 4a–l. The inhibitory activity
