This paper presents the preparation of a pyrazoline compound and the properties of its UV-Vis absorption and fluorescence emission. Moreover, this compound can be used to determine Hg2+ ion with selectivity and sensitivity in the EtOH:H2O=9:1 (v/v) solution. This sensor forms a 1:1 complex with Hg2+ and shows a fluorescent enhancement with good tolerance of other metal ions. This sensor is very sensitive with fluorometric detection limit of 3.85×10-10 M. In addition, the fluorescent probe has practical application in cells imaging.

1-Benzimidazolyl-3-aryl-prop-2-ene-1-ones 2 have been transformed into N1-substituted pyrazoline derivatives by the interaction with phenyl hydrazine, thiosemicarbazide and hydrazine hydrate in the presence of formic acid under solvent microwave induced protocol. The structure of newly synthesized compounds have been confirmed on the basis of their elemental analysis and spectral data. Newly synthesized compounds have been evaluated for their antimicrobial activity in against E. coli, K. pneumonae, P. aeruginosa and B. subtilis using paper disc method. Some of the compounds have shown significant activity against the pathogens.
