A bifunctional fluorescent probe 1,1'-(5,5'-(6,6'-dihydroxy-5,5'-dimethoxybiphenyl-3,3'-diyl)bis(3-(2-hydroxy-phenyl)-1H-pyrazole-5,1(4H,5H)-diyl))diethanone (C1) based on bispyrazoline was designed and synthesized. The structure of C1 was confirmed by 1H NMR, 13C NMR, MS and elemental analysis. The spectroscopic behavior toward metal ions has been investigated by the absorption and fluorescence methods. It exhibited high sensitivity and selectivity for detecting Cu2+ and Zn2+ over other commonly coexistent metal ions in 4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid (HEPES) buffer solution[V(MeOH):V(H2O)=1:1, 20 mol·L-1, pH=7.4] and it has the capability to differentiate target ions with different flu-orescence.

Key words: bispyrazoline, bifunctional, fluorescent probe, copper ion, zinc ion
