A fluorescent-colorimetric azo dye based bis-Schiff base chemosensor, L, has been developed. L can selectively detect S2− through a color change from yellow to orange in perfect aqueous solution by deprotonation mechanism.
A novel triazole-based bis Schiff base colorimetric and fluorescent chemosensor (L) has been designed, synthesized and characterized. The chemo-sensor L shows its application potential in the detection of Cu2+ and Pb2+ in living cells and building molecular logic gate.
A new rhodamine 6G-benzylamine-based sensor (L1) shows selective recognition of trivalent metal ions with advanced level molecular logic gate and bio-imaging applications.
A new azo based chemosensor for detection of Al3+ ion has been reported. The sensor has been well characterized using different techniques like single crystal X-ray, NMR, IR, UV etc. Detection limit of the chemosensor was found to be 6.93 nM.
