中文摘要：

porphyrin-perylenediimide 二的分子的聚集状态能被与 trifluoroacetic 酸对待改变。当二从中立溶剂猛抛时，发射度电子显微镜学(TEM ) 图象表明薄片微观结构被形成，但是当从酸的答案猛抛时，球形的 nano 粒子被获得。X 光检查衍射模式证明薄片微观结构和 nanoparticles 是多晶的并且无定形固体分别地。由把合理 perylenediimide 和卟啉用作参考混合物，在不同条件下面的二和参考书的紫外可见的系列上的小心的分析被进行，结果证明二的卟啉和 perylendiimide 子单元在中立溶剂拿了J聚集，但是在与 trifluoroacetic 酸和氯仿答案被对待以后，当卟啉子单元改变了到一个随机的收拾行李模式时， perylenediimide 子单元改变了到H聚集。

英文摘要：

The molecular aggregation state of a porphyrin-perylenediimide dyad can be changed by treating with trifluoroacetic acid. Transmittance electron microscopy （TEM） images revealed that lamella microstructures were formed when the dyad precipitated from neutral solvent, but spherical nano-particles were obtained when precipitating from acidic solution. X-ray diffraction patterns showed that the lamella microstructures and the nanoparticles were polycrystalline and amorphous solids, respectively. By using rational perylenediimide and porphyrin as reference compounds, careful analyses on the UV-visible spectra of the dyad and the references under different conditions were conducted and the results demonstrated that both the porphyrin and perylendiimide subunits of the dyad took J-aggregation in neutral solvent, but after being treated with trifluoroacetic acid and chloroform solution, the perylenediimide subunit changed to an H-aggregation while the porphyrin subunits changed to a random packing mode.
