摘　　要：成功制备新型有机多并苯环分子材料Ph-OMe,系统研究其紫外吸收、荧光光谱和荧光量子产率。通过光谱测试和理论计算,对有机多并苯环分子材料Ph-OMe的光学性质和荧光量子产率进行考察,结果表明,有机多并苯环分子材料Ph-OMe呈现蓝色的荧光,荧光量子产率约为8%,体现出潜在的蓝色发光特性。通过研究有机多并苯环材料的荧光特性,探讨有机多并苯在发光领域的应用前景,为构建性能优异的发光材料与器件提供有效的思路。A novel organic azaacene molecule Ph-OMe has been successfully prepared.The UV-vis absorption spectra,fluorescence spectra and fluorescence quantum yield of Ph-OMewere systematically investigated.Through spectral analysis and theoretical calculation,we examined the optical property and fluorescence quantum yield of Ph-OMe.The result indicates that Ph-OMe exhibits blue fluorescence and that the fluorescence quantum yield is about 8%,which demonstrates the potential of blue luminescence characteristics.By investigating the fluorescence property of Ph-OMe and discussing the application prospect of organic azaacene materials in the luminescence field,this paper offers an efficient idea for constructing high performance luminescent materials and devices.
