[Abstract]
Polymers are essential in our daily life- plastic bags, clothes, house furniture, electronic devices, and vehicles etc. The number of applications is countless. One of the recently developed polymers is high porosity and crystallinity, called porous crystalline polymers (PCPs; covalent organic frameworks and metal-organic frameworks). The two unique features of PCPs, permanent porosity and crystallinity, make them useful in sustainable engineering applications. Covalent organic frameworks with ionic functional groups can transport ions (e.g., Li+ or Zn2+) rapidly in a reliable manner. Those ionic covalent organic frameworks are incorporated in energy devices for enhanced performance. For instance, metal-organic frameworks with functionalized chelating groups can remove contaminants. The adsorption performance, in this case, outperforms any other known adsorbents. The chemical principles guide us to design PCPs with tailored functional groups, targeted surface area, desired connectivities and morphologies, and compositions on demand. Overall, the advantages of porosity, periodicity, tailorability, and modularity make the PCPs ideal materials for sustainable engineering in water and energy.
