Abstract
Transition metal catalysts immobilized on the surface of MOFs, are being utilized for an ever increasing number of reactions ranging from couplings to olefin oligomerization. While these reactions are usually performed in solution, unlike their homo-geneous counterparts, the insolubility of the MOF systems makes it difficult to obtain detailed mechanistic information by in situ spectroscopic analysis in solution. In this report, we present a synthetic method to solubilize these systems by grafting oligomers on the surface of the MOF particles, making it possible to characterize these species by transmission IR spectros-copy. The fundamental photochemistry of these catalysts was also studied and compared to that of their homogeneous counterparts. This work establishes a proof of principle for in solution monitoring of heterogeneous catalysts.Keywords
