| Outline of Research at the Start |
I will use porous molecular cages (MOPs) to immobilize catalyticaly active metal nanoparticles (MNPs) within host cage. In addition, metal-organic cages offer the advantages such as flexibility and processability, which will be use to control the assembly of the hybrid system MNPs(guest)/MOPs(host) into porous gels. The system will be used as bifunctional membrane offering extra free hierarchical porosity for optimal reaction-diffusion and perform one-pot multi-steps catalysis.
This work could lead to high impact journals publication and presentation in international conferences.

| Outline of Final Research Achievements |
As porous molecular solids, MOPs present improved prospects for materials processing. They have been used as templates to accommodate and control properties of various guests. However, the joint use of (i) the intrinsic cage porosity with the extrinsic porosity of MOP-assembled structure and (ii) the compartmentalized catalytic sites into a MOP-based gel for tandem catalytic applications has never been described. The originality of the project lies in the use of MOPs to (i) isolate multiple catalytic species; (ii) control their spatial organization during gel formation and (iii) use the mesoporosity created by the gel networks as diffusion channels for reactants to create a bifunctional catalytic porous membrane for continuous reactions. The work will demonstrate new applications for porous molecules not only in the field of catalysis but also for selective sensing and chiral separation.
