Covalent organic frameworks are a new class of crystalline materials that are made by linking organic building units through strong covalent bonds. Owing to the ability to precisely control the geometry and functionality of extended structures, Yuzhong designed and synthesized weaving materials that are resilient yet robust. By using the copper-bisphenanthroline templated approach, organic threads are woven into extended frameworks with atomic precision; these templates can be removed post-synthetically, leading to higher degrees of freedom in the structure while preserving the underlying connectivity. The dynamic nature and chemical stability of such materials allows for heavy metal sequestration from water and CO2 reduction upon incorporation of electrocatalysts such as cobalt-porphyrin.
