 Abstract this study demonstrates the successful recovery of homogeneous photocatalysts from organic solvents using covalent organic frameworks, COF. This methodology can be used to recover photocatalysts at grand scale and has the potential to revolutionize the field of organic synthesis. Applications the successful recovery of homogeneous photocatalysts from organic solvents using COF membranes has the potential to revolutionize the field of organic synthesis. This methodology can be used to recover photocatalysts at grand scale and can be applied to a wide range of applications such as pharmaceutical and fine chemical synthesis.
