A new turn-off probe 6 was synthesized from bis(pyridin-2-ylmethyl)amine and truxene derivatives, and its structure was confirmed by 1H NMR and HRMS. The recognition behaviors of 6 to various metal ions were investigated and the results show that 6 exhibited good selectivity and high sensitivity to Cu2+ and Ni2+ with good anti-interference. The probe 6 presented apparent fluorescence quenching in DMF/H2O (V/V=8/2, pH=7.0) solution toward Cu2+ and Ni2+. HRMS analysis showed a 1:1 binding stoichiometry between 6 and Cu2+ or Ni2+. The detection limit for Cu2+ and Ni2+ was calculated to be 28 and 41 nmol/L, respectively. The detection limit of 6 for Cu2+ and Ni2+ was far lower than the maximum allowable level of World Health Organization (WHO) limit for drinking water.

Key words: truxene, bis(pyridin-2-ylmethyl)-amine (DPA), fluorescent sensor, Cu2+, Ni2+
