Abstract: A monosubstituted rhodamine-based thiacalix 4 arene derivative(1 was synthesized from cone 1, 3-bis
(hydroxycarbonyl-methoxy)thiacalix[4 Jarene and rhodamine B ethylenediamine by acylation. Its structure wa
characterized by IR, NMR, MS and Elemental analysis. Fluorescence and UV absorption spectra studies showed
that it can be used as a selective chemosensor for Fe*. In the ethanol aqueous medium ( 1/1, V/, TRIS-HCI
buffer, PH=6.0), the derivative showed OFF-ON light response to Fe. The presence of Fe*induced a significant
fluorescence enhancement, and a distinct color change from colorless to red was observed. The formation,
stability constant and fluorescence quantum yield of the Fe*-complex were calculated, respectivel
Key words: rhodamine; thiacalixl4jarene derivative; luorescent and colorimetric chemosensor; Fe-complex
