(2D) imine-linked covalent organic frameworks (COFs)
have attracted great interest for gas uptake, catalysis, drug delivery,
electronic devices, and photocatalytic applications. The synthetic
methodologies involved in imine-linked COF formations such as solvothermal
synthesis usually require harsh experimental conditions. In this work,
we show for the first time how highly crystalline COFs with very high
surface areas (3.6 times higher than using conventional approaches)
can be prepared by combining a mechanochemical and crystallization
approach. More importantly, this facile method is a general route
to novel composites of COF and metal oxides including Fe3O4, Co3O4, and NiO. The composites
can be used as magnetically recoverable adsorbents and show a strong
redox-activity making them interesting for applications in electrochemical
energy storage.
