A zinc supracluster [Zn(ATZ)(AcO)(HO)]·(HO) (), and a 1D zinc supracluster chain {[Zn(ATZ)(AcO)(CHOH)(HO)]·(HO)} () with molecular diameters of 2 nm were synthesized under regulatory solvothermal conditions or the micro bottle method. In an N,N-dimethylformamide solution of , Fe, Ni, Cu, Cr and Co ions exhibited fluorescence-quenching effects, while the rare earth ions Ce, Dy, Er, Eu, Gd, Ho, La, Nd, Sm, and Tbshowed no obvious fluorescence quenching. In ethanol solution, the supracluster can be used to selectively detect Ce ions with excellent efficiency (limit of detection (LOD) = 8.
