[Synthesis of new pyrazoline fluorescent compounds and their IR spectra and fluorescence property].

The Fluorescent compounds of pyrazoline have been used in many field. According to Schellhammer theory, we designed and synthesized five new benzothiazoyl pyrazoline compounds. Their infrared spectra and fluorescent spectra of five compounds were detected. The results showed that five compounds have fluorescence, fluorescence emission wavelength is about 450nm. Effect of different substituents on the fluorescent intensity was investigated.
