| Outline of Annual Research Achievements |
I worked mainly on the self-assembly of cationic metal-organic polyhedra (MOPs) with anionic polyoxometalates (POMs). When soluble precursors solutions are mixed, a precipitate (POM-MOP) is formed instantly, with a crystalline ordering and porosity . POM functionality is enhanced when immobilized in the porous network , as demonstrated with hydrazine vapor reaction. This work was recently published in Chemical Communications.
I also worked on ionic derivative of neutral MOPs. The synthesis was successful, and will enable the study of the physical chemistry properties for such macro-ions.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
Despite COVID, some laboratory work could be performed. The results could be already summarized in an article. The project will continue with the combination of other MOPS, with other POMS or other types of functional ions.
|
| Strategy for Future Research Activity |
After a proof of concept concerning the assembly of POM and MOPs, we plan to expand the scope of structures. In particular, choosing other charges of POMs will allow to reach different types of network connectivity. Another topic of research will be the in-situ reduction of the POMs in the assemblies, to produce highly efficient sensor, or even chemically responsive networks.

| Causes of Carryover |
The fund will be used mostly to purchase chemical reagents, consumables and pay for external analytical services. I also consider buying small lab equipment (hotplate stirrer, pressure gauges,...) or glassware, depending on the project needs that may appear.
Some software licenses will need renewal soon (Adobe illustrator notably), and some funds will be used to modernize informatic equipment in my office (Monitor and printer).
