Abstract：A symmetrical rhodamine-triazine derivative was synthesized through step-by-step substitution of rhodamine B ethylenediamine with two chlorines on cyanuric chloride. It showed an extreme selectivity for Al3+ and Cr3+ over other common metal ions and strong fluorescence emission and UV-Visible absorption in the ethanol solution of pH 4. Due to the difference in complexing ability, the recognition of the derivative for Al3+ and Cr3+was not interfered by other coexisting ions. Under certain conditions, the derivative can be used as high selectivity and high sensitivity Al3+ or Cr3+ fluorescence and colorimetric enhanced probe.
