Covalent organic frameworks (COFs) are new materials that have various characteristics like porosity, structural regularity, and functionality. In this study, we synthesize perylene-based COFs and perylene-based COFs are used for removal of heavy metals with those characteristics. Perylene-based COFs have been prepared by imidization reaction with perylene dianhydride (PDA) and 5, 10, 15, 20-Tetrakis(4-aminophenyl)porphyrin. And PDAs were substituted with polarity functional groups like hydroxyl groups, amine groups at perylene bay position. These functional groups can capture and remove heavy metals by coordinate covalent bond with metal cations. |
