【Abstract】 A derivative of the pyrazoline,which was 1-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 expectation. The fluorescence excitation and emission spectra of target compound in ethanol were measured,and it was found that the maximum excitation wavelength was 378. 4 nm and the maximum emission wavelength was 488. 4 nm.更多还原
