卟啉和相关的四吡咯已经被广泛研究，因为它们在生物过程中的重要性，并且它们经常被用于人工光合作用、催化和传感器系统的开发。功能性纳米卟啉系统的开发面临着许多挑战，包括需要组织卟啉（例如，例如，在一个实施例中，以促进诸如能量和电子转移的过程）和将卟啉纳米结构偶联到其它纳米级组分（例如，例如，在一个实施例中，催化元件和导体）以产生多功能纳米级系统。本文综述了近年来在卟啉自组装纳米结构的合成方面的研究进展。还描述了一种在卟啉纳米结构上生长金属以产生具有金属催化剂或互连的纳米复合材料的新方法。这些纳米结构和卟啉金属纳米复合材料的当前和潜在的应用进行了讨论。
Porphyrins and related tetrapyrroles have been extensively studied because of their importance in biological processes and they are often used in the development of artificial photosynthesis, catalysis, and sensor systems. Challenges in the development of functional nanoscale porphyrin systems are many, including the need to organize the porphyrins (e. g., to facilitate processes such as energy- and electron transfer) and to couple the porphyrin nanostructures to other nanoscale components (e. g., catalytic elements and conductors) to produce multifunctional nanoscale systems. This article summarizes recent advances in the synthesis of discrete self-assembled porphyrin nanostructures with well-defined shapes and sizes. A novel method for growing metal on the porphyrin nanostructures to produce nanocomposites with metal catalysts or interconnects is also described. Current and potential applications of these nanostructures and porphyrin-metal nanocomposites are discussed.
