In the present paper, a kind of blue light-emitting organic small molecule luminescent materials was designed and synthesized, which is composed of carbazole and 8-benzyloxyquinoline functional groups. Alkyl chain can effectively play the role of electron transfer barrier. The synthesis principle was on the basis of the mechanisms of SN1nucleophilic reaction and SUZUKI coupling reaction mechanisms. It is entitled N-［6-(8-benzylquinoline)-hexyl］carbazole (CZBQ). Its molecular structure was simulated and optimized by Gaussian03. Its chemical structure was identified by measurements of ultraviolet-visible spectra and H1　NMR spectra. It photo physical property was characterized by method of fluorescence spectra. t is indicated that CZBQ was a kind of blue-light luminescence material and its optical band gap is 3.02　eV. Ethanol solution of CZBQ exhibits the maximal emission peak at 410　nm in photoluminescence spectra. In the luminescence process of CZBQ, carbazole groups and 8-benzylquinoline groups were separately involved in excitation and light emission. This kind of blue-light luminescence material possesses excellent solubility, It can be dissolved in different solvents such as ethanol and ethyl acetate and dichloromethane.　The test results of AFM show that CZBQ was provided with very good film formability. It is expected to be utilized in blue-light organic light-emitting device fabricated by wet method such as spin-coding method and screen printing.
