Porphyrin containing proteins such as heme, cytochromes, and chlorophyll have been studied for their interesting biological functions such as oxygen transport, storage, and electron transfer. According to recent studies, porphyrin distortions (non-planar porphyrins) play a key role in the controls the functions such as redox potential, and binding affinity. There have been many studies on the relationship between non-planar porphyrins and biofunctions on the supramolecular chemistry. However, numerous researches have been done with non-planar porphyrin molecules on the molecular level, the field of porous materials is still its infancy.
In this work, we successfully obtained new 2D porphyrinic MOF, UPF-100 (UPF represents UNIST porphyrin framework) constructed with elongated non-planar porphyrin ligand and copper paddle wheel. UPF-100 show unique structural characteristics such as waved layer sheets and zig-zag pore channels. In addition, we synthesized UPF-100 nanosheets via surfactant-mediated protocols. We show that UPF-100 can the impact fundamental research as well as energy applications.
