Highly Sensitive and Selective Colorimetric and Off-On Fluorescent Reversible Chemosensors for Al(3+) Based on the Rhodamine Fluorophore
A series of rhodamine derivatives L1–L3 have been prepared and characterized by IR, (1)H-NMR, (13)C-NMR and ESI-MS. These compounds exhibited selective and sensitive “turn-on” fluorescent and colorimetric responses to Al(3+) in methanol. Upon the addition of Al(III), the spiro ring was opened and a...
