| 摘 要： | 制备了不同类型的巯基卟啉自组装膜，借助多种表征技术（紫外可见光谱、电化学和X射线光电子能谱）研究了不同类型卟啉自组装膜的结构特点；研究结果表明，卟啉分子中巯基取代基数目的不同（-SH]n-，n=1,4），导致了卟啉环在自组装膜表面的构型不同，从而表现出不同巯基卟啉自组装膜性能的差异。 在此基础上，提出了不同巯基卟啉自组装膜的结构模型。

| Abstract: | Different self-assembled thiol-substituted porphyrin monolayers(TPPS1 and TPPS4) were prepared and characterized by means of UV-Vis, CV, EIS and XPS. The results showed that the self-assembled porphyrin monolayers have different configurations due to the different numbers of the thiol-substitute in porphyrin molecules. Therefore, these porphyrin monolayers showed different performance in catalysis. On the basis of those observations, we proposed a model for the assembling of multi-thiol substituted porphyrin into monolayer. The established method shows potential for building and developing functional self-assembled porphyrin monolayers in the application of bio-catalysis and optoelectronic devices. |
