摘要：

以3(4)-硝基邻苯二腈和对甲氧基苯酚为原料, 经过两步反应合成了α(β)-四(4-甲氧基苯氧基)酞菁锌, 通过谱学方法和元素分析表征了其结构. 比较研究其溶液和旋涂膜的紫外可见光谱、光致发光光谱和固体薄片的光致发光光谱. 并以其旋涂膜为发光层制备了电致发光器件, 研究其电致发光性质. 结果表明, 固态酞菁材料与其溶液的荧光发射波长相比均向长波方向移动了145 nm以上, 而且都有不同程度的宽展. 在固态下β-位取代酞菁荧光发射波长红移的程度比α-位取代酞菁大. 电致发光光谱的发射波长和其旋涂膜的光致发光光谱的发射波长基本一致, 大约在856和862 nm左右. 在固态下酞菁分子排列紧密, 分子间相互作用增强导致了荧光发射波长的巨大红移.

Abstract:

α(β)-tetra-(methoxy-phenoxy)-zinc phthalocyanine are synthesized by employing 3(4)- nitrobenzene-1,2-dicarbonitrile as precursors. They are characterized by spectrum methods and elemental analysis. The UV-Vis spectrum, photoluminescence spectra of spin-coated film and solid pellet are compared. The electroluminescent devices are fabricated by using spin coating. The results indicate that the fluorescence of solid phthalocyanine has a red-shift of more than 145 nm compared to that in solution. The fluorescences are broader in solid state than that in solution. The fluorescence of β-substituted phthalcyanines has a more red-shift than α-substituted phthalcyanines. The electroluminescent spectra around 856 and 862 nm are consisted with the photoluminescence spectra of spin-coated film. The shorter inter-molecule space leads to the large red-shift of the fluorescence.
