Modular Construction of a Porous Organometallic Network Based on Rhodium Olefin Complexation

We describe the rational design and synthesis of the
first member
of a new class of microporous materials. It is built from rhodium
and a polyolefinic ligand featuring a rigid tetraphenylsilane backbone
via metal olefin complexation, creating a truly organometallic network.
The resulting framework, denoted as DUT-37 (Dresden University of
Technology no. 37) exhibits considerable porosity and unprecedented
stability under ambient conditions. Furthermore, it is catalytically
active in transfer hydrogenation.
