Öğe Synthesis and spectroscopic studies of novel rhodanine azo dyes: An excellent selective chemosensor for naked-eye detecting of Cu 2+ Ion(2012) Ceylan A.; Baş S.Z.; Bayrakci M.; Ertul S.; Uysal A.This study is first report on the synthesis of novel rhodanine based azo dyes and their fluorogenic and chromogenic sensing behaviors with metal ions (Li +, Na +, K +, Rb +, Pb 2+, Ni 2+, Zn 2+, Cu 2+) by using UV-vis and fluorescence spectroscopy techniques. The results of spectroscopic experiments for rhodanine based azo dye 1a exhibited excellent selectivity for Cu 2+ over the other metal ions. Furthermore, anti-bacterial studies of rhodanine azo dyes were performed towards some selected bacteria via microbroth dilution method. Obtained results showed that rhodanine ionophore 1a showed strong antibacterial activity against S.aureus.
