Synthesis of 1-phenyl-3- (β- pyridyl) -5- (α- furanyl) pyrazoline

A derivative of the pyrazoline, which was1-phenyl-3-(beta pyridyl)-5-(alpha furan) pyrazolin, was designed
and synthesized. The molecular structure of the target compound was speculated by IR, GC and MS and is up to our expecta- tion. The fluorescence excitation and emission spectra of target compound in ethanol were measured, and it was found that the maximum excitation wavelength was378. 4nm and the maximum emission wavelength was488. 4 nm.
