通过SN1亲核反应机理及SUZUKI偶联反应,设计并合成了一种含有咔唑及8-苄氧基喹啉基团的有机蓝光发光材料,即N-[6-（8-苄氧基喹啉基）-己基]咔唑（CZBQ）。通过紫外-可见吸收光谱和荧光光谱等测试方法对其结构及光物理性能等进行了表征。研究结果表明：CZBQ为一种蓝光有机发光材料,其光学带隙为3.02eV,在乙醇溶液中的发射峰波长为410nm;CZBQ具有优良的溶解性和成膜性,适用于湿法制备蓝光有机电致发光器件。
英文摘要：
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.
