Chemically reactive membrane formation method using macrocyclic ligands
A patent application (Publication Number: US20240033720A1) describes a method for forming a chemically reactive membrane. The process involves applying a first solution containing a macrocyclic ligand with electron-donating ligands and a crosslinking functional group to a structure, forming a network of crosslinked macrocyclic ligands. A second solution with a catalytic center is then applied, forming catalytic sites within the network. The macrocyclic ligand can be selected from cyclen, cyclam, porphyrin, or DOTA, and the catalytic center can be a metal cation like zinc or copper.
Furthermore, the method allows for the creation of multiple networks of crosslinked macrocyclic ligands with different catalytic sites by applying additional solutions with different macrocyclic ligands and catalytic centers. The process involves crosslinking the second macrocyclic ligand to form a second network and applying a fourth solution with a second catalytic center. The functional groups for crosslinking and the catalytic centers in the first and second networks can be different, providing versatility in the types of catalytic reactions that can be facilitated by the chemically reactive membrane. This method offers a novel approach to creating membranes with tailored catalytic properties for various applications, with the potential for customization based on specific catalytic needs.
