Abstract: Thirteen of 1 ,4-Bis(1',3'-Benzbxazblyl-2') -benzene derivatives are synthesized, they are all new compounds. Their m. p., IR, UVabsorption spectra, fluorescence emission spectra, fluorescence quantum efficiencies, fluorescence lifetime as well as laser conversion efficiencies of the compounds are determined. The results obtained show that the absorption maximum is at 330-350nm and the fluorescence maximum at 385-406nm. In comparison with unsubstituted compound they have lower melting points and higher solubilities. These compounds are moree coplanar and higher fluorescence quantum efficiencies. The compound ⅩⅢ reported here has a. higher laser conversion efficiency than those other ones of homologous (10% above) and is photochemically stable.
