摘要：卟啉及其衍生物是一种大环共轭芳香的化合物，因此具有很好的光电性能和生物特性。近年来，卟啉类化合物因其在仿生学、生命科学、医学、质地学、电化学、光物理与化学、分析化学、有机化学等范畴存在可操作远景而获得人们的普遍关心。与此同时，自组装膜因其有序、稳定、结构多样等特性而被广泛应用于光电器件、传感、催化等领域。我们工作的首要任务正是将卟啉与自组装技术结合，构建有序的功能化超分子膜。本论文将设计并合成卟啉单体，利用其轴向与周边取代基的反应活性进行自导向组装，构建生长方向可控、厚度可控、光电转换效率高而且稳定的卟啉复合薄膜。将卟啉与自组装技术相联系，对于创造出有序的公用性超分子膜拥有重要意义。24371

Assembly of porphyrin composite films
Abstract: Porphyrin are a kind of macro cyclic conjugated aromatic compounds with favorable optoelectronic properties and biological activity. In recent years, considerable attention has been paid on porphyrin compounds owing to their potential applications in bionics, life sciences, medicine, materials science, electrochemistry, photophysics and chemistry, analytical chemistry and organic chemistry. At the same time, on account of the characteristics of well-order, stable, various properties and pre-designed structure, self-assembled film of porhyrin has been widely applied in the electronic and optical devices, chemical sensors, biological sensors, catalysis, and other research fields. It has been the focus of considerable research activity. In this thesis, a new kind of porphyrin monomer with special reactivity was designed and prepared. By using the reactivity of axial and peripheral substituent of the monomer, two and three-dimensional stable thin films of pophyrin were fabricated by self-directed assembly of the monomers. The achieved porphyrin films were with great advantages of controlled growth direction, thickness and high photoelectric conversion efficiency. The technique by combining porphyrin and self-directed assembly was very important to construct orderly functional thin films of porphyrins.
