Porous Organic Frameworks: Synthetic Strategy and Their Applications

Porous materials have been intensively applied in fields of ion exchange, adsorption and separation, host-guest chemistry, etc. The development of porous materials has fundamental and practical significance. Based on the component and constructing bond of porous materials, they include zeolite, mesoporous materials, metal-organic frameworks (MOFs) also known as coordination polymers, and porous organic frameworks (POFs). Compared with other porous materials, POFs could be considered as a new star. POFs are constructed by the designable and tunable organic building units (OBUs) via robust covalent bonds. Therefore, POFs display a series of advantages, such as diverse skeletons, high stability, high surface area, tunable pore, etc. The synthesis procedure could be described as the assembly of building units via specific acting force. In this review, we will introduce the synthetic principles, gas storage, catalysis, and other applications of the advanced POFs.
