合成并表征了化合物:1,6,7,12-四(4-对叔丁基苯氧基)-3,4;9,10-苝二酐,利用再沉淀法制备了不同粒径的-维有机纳米材料,并用TEM对其结构进行了表征。分析了纳米材料的生长过程,讨论了有关的机理。用吸收光谱和荧光光谱法研究了化合物3含量变化对聚集的影响,纳米材料的吸收光谱显示存在J-型聚集结构的新吸收峰,并伴随有吸收峰的红移;通过与其对应的分子荧光光谱比较,发现聚集体荧光光谱发生了红移,且荧光被淬灭。
[1, 6, 7, 12-- tetra (P-- tert-- butyl) phenoxy] perylene-- 3, 4 ; 9, 10-- tetrarboxylie dianhydride was synthe- sized and characterized. One dimensional organic nanostruetures with different sizes were prepared via reprecipitation method and characterized by TEM. The growth process of the nanowires was also analyzed and discussed. The effects of compound 3 content on aggregation were studied using fluorescence and absorption spectra. A new J-aggregate absorption peak with a red shift appeared in the absorption spectra of nanostructures. In comparison with the fluorescence emission spectra of aggre- gation and molecules (in tetrahydrofuran solution), it was indicated that aggregation fluorescence spectra are red--shifted and cancellation.
