In recent years, photopolymerization has been rapidly developed and has become an integral part of life and production. Because of economy, environmental friendly, high efficiency, photopolymerization has been widely used in many traditional and emerging areas, such as coating, adhesive, ink, dental restoration, three dimensional precision,3D printing, etc. MOFs (Metal-Organic Frameworks) introduced in the 1990s, are an emerging class of three dimensional porous crystalline materials constructed by metal-containing nodes connected by organic bridges. Due to the large porosity, large specific surface area, adjustable structure and chemical properties, MOFs have widely used in gas storage, separation, catalysis, sensors, biological medicine and so on. This topic combines photopolymerization and MOF, making full use of their advantages and characteristic. Main contents and conclusions are as follows:1. The photopolymerizable organic ligand was synthesized successfully, and the organic ligand had good photochemical activity;2. Photopolymerizable Uio-66-liked Zr-MOF, which had uniform morphology and diameter, was prepared by the photopolymerizable organic ligand. Then, we used the method of "photopolymerization after self-assembling" to prepare macroporous structure, octahedral-like morphology, three-dimensional porous polymer particles via combining photopolymerization and MOF;3. As photopolymerizable monomer, Acrylic Acid can be used as MOF nucleation and growth sites. Several polymer substrates with different content of carboxylic groups were prepared quickly and simply through photopolymerization, then, the intergrown MOF films were obtained by the method of direct synthesis. The effects on MOF growth on the polymer substrates by the additional content of Acrylic Acid were also studied;4. Through photopolymerization, patterned polymer substrates were prepared, and patterned intergrown MOF films were obtained. The resolution can reach micron grade.
