Advanced Synthetic Techniques and Emerging Applications of Porphyrin Paddlewheel Frameworks
Controling the assembly of metal-organic frameworks (MOFs) using metalloligands (ligands containing a metal ion within the molecule) has been of particular interest in materials research due to these materials' ability to create porous structures with chemically active metal sites in the internal pores. MOFs are a class of organic-inorganic hybrid materials which are constructed through the coordination of multitopic organic linkers to metal ion nodes. A seemingly endless array of 1, 2, and 3D topologies are possible through judicious selection of the organic linker and metal ion source. Additionally, with the inclusion of metalloligands, a variety of functionality can be included into these MOFs, making them suitable for a variety of applications such as gas storage or catalysis. As a result, the development of advanced synthetic techniques to make these materials and continued search for new applications is very important. One emerging advanced synthetic approach is a sequential self-assembly (SSA) strategy in which a simple MOF structure is initially synthesized through traditional methods, and used as a template for subsequent self-assembly processes creating new highly pure products. Herein we demonstrate the use of SSA on Porphyrin Paddlewheel Frameworks (PPFs)—a class of MOFs created with a porphyrin metalloligand. In addition, we present emerging applications in catalysis, fluorescence sensing, gas storage, and optical dichroism of these PPFs.
