Abstract Benzothiazole compounds with byrazoline group or benximidazole group are new fluorescent compounds. The fluorescent compounds have been used in many fields, but their development has beeo slow. According to Schellhammer theory on the relation between chemical structure and fluorescent quality, the authors designed now fluorescent compounds with benximidazole group or the byrazoline group in the 1-benzothiazole and with biphenyl in the 3,5-benzothiazole, and their possess fluorescent nature. Two new benximidazole and benzothiazole fluorescent compounds were synthesized. All these compounds were characterized by elemental analysis and infrared spectroscopy. The excitation wavelength of the two compounds is about 441-446 nm. The fluorescence spectra show that the compounds have good blue and green fluorescence. The characteristic peaks of the absorption spectra of these compounds were found by IR spectral analysis, which can be used to deduce the structures of chemical compounds.
