Abstract

A luminescent coordination cage formulated as {Mg₂₄(TC4A)₆(BTC)₈(H₂O)₆} (SWU-2, H₄TC4A = p-tert-butylthiacalix[4]arene, H₃BTC = 1,3,5-benzenetricarboxylic acid) was successfully synthesized by the assembly of Mg₄-TC4A units with BTC ligands. SWU-2 shows excellent fluorescence characteristics in aqueous solution and in the solid state. Luminescence sensing experiments indicated that SWU-2 exhibits obvious fluorescence quenching for Fe³⁺, MnO₄,⁻ nitrobenzene (NB) and 2,4-dinitrophenol (2,4-DNP) in aqueous medium and can be regarded as a high sensitivity sensor for detecting Fe³⁺, MnO₄⁻, NB and 2,4-DNP.
