Popis:	A novel pyrazoline derivative, 2-(4-chloro-2-(1-(6-chloropyridazin-3-yl)-5-phenyl-4,5-dihydro-1H-pyrazol-3-yl)phenoxy)acetic acid , was synthesized starting from a chalcone and 3-chloro-6-hydrazinylpyridazine and proposed for the determination of Zn 2+ ion with high selectivity and a low detection limit in CH 3 CN:EtOH (90/10, v/v). This sensor formed a 1:1 complex with Zn 2+ and showed a fluorescent enhancement with good tolerance of other metal ions.
