Polyoxometalates self-assembly process

An alternative strategy for the functionalization of polyoxometalates relies on self-assembly processes. Up to now we failed to introduced a Schrock-type alkylidyne in the lacunar undodecaphosphotungstate. As the current trend in olefin metathesis reaction now favours ruthenium catalysts, such as the Grubbs s ones, we turn to ruthenium precursors and to more stable Lappert-type carbene fragments, stabilized in the a-position by nitrogen atoms. The reaction of [PWii039p- with the carbene precursor... 

In summary, the choice of polyoxometalates as a building block system to develop approaches to artificial inorganic life may seem outlandish, but I hope that I have demonstrated that the rich structural architectures and self assembly processes required to construct such architectures will inspire future work. Certainly... 

Understanding fundamental uranyl polyoxometalate chemistry in solution and the SS is the 1st step to defining its future role in the development of new actinide materials and separation processes that are vital to every step of the nuclear fuel cycle. Many SS geometries of uranyl polyoxometalates were described, but the authors are only beginning to understand their chemical behavior, which thus far includes the role of templates in their self-assembly, and the dynamics of encapsulated species in solution This study provides unprecedented detail into the exchange dynamics of the encapsulated species in the SS through MAS NMR spectroscopy. ...
