The recent research progress and application of nanoparticles and ions supporting by covalent organic frameworks.

Covalent organic frameworks (COFs) are promising for catalysis, adsorption, separation, etc. owing to unprecedented combination of the large surface area, high crystallinity, tunable pore size, and unique molecular architecture of COFs. Just because of the above-mentioned merits, COFs can be ideal support for quite a few kinds of small materials with unstable nature, such as nanoparticles, ions, quantum dots, single atoms and so on. With COF support, those species can not only exist stably, but also readily be applied in various fields. Herein, the recent advances in the design and synthesis of COF-support hybrids for various applications are presented. Also, future research directions and perspectives are discussed for the development of efficient COF-support hybrid materials. [Display omitted] • Introduce the effect on the nanomaterial with modification of COFs. • Describe the application and development of COF-loaded metal nanoparticles, metal ions and compounds in recent COF reports. • Briefly Describe the possible development direction of COF-based hybrids in the future.
