摘　　要：采用电化学循环伏安法和紫外光谱法对系列基于异佛尔酮红色发光材料(DNP-2CN、DPN-2CN、DPN-4CN、NNCa-2CN、PNCa-2CN和PNCa-4CN)的电化学性质进行了研究,并通过紫外光谱法和荧光光谱法测定了此系列材料的光学性质。此类材料均为电子受体-电子给体结构,具有相同的电子受体基团-共轭多腈,不同的电子给体基团-三芳香胺或者N-芳香基咔唑。讨论了分子结构对于化合物的电子能级结构、吸收光谱以及发射光谱的影响。The electrochemical properties of red fluorescent materials（ DNP- 2CN, DPN -2CN, DPN - 4CN, NNCa- 2CN, PNCa- 2CN and PNCa-4CN） based on isophorone were studied by cyclic voltammetric experiments and the absorption spectra. The optical properties were observed by the absorption spectra and photolumineseenee spectra. These materials have the same molecular structure： donor-π - aeeeptor, with dieyanomethylidene as the electron - acceptor and triarylamine or N - aryl - amine as the electron -donor. The effects of molecular structure on the electronic level structure of the molecule and the optical properties were also explored.
