Investigations into Asymmetric Post-Metallocene Group 4 Complexes for the Synthesis of Highly Regioirregular Polypropylene
Single-Site Organozirconium Catalyst Embedded in a MetalâOrganic Framework
A structurally well-defined mesoporous
Hf-based metalâorganic
framework (Hf-NU-1000) is employed as a well-defined scaffold for
a highly electrophilic single-site d<sup>0</sup> Zrâbenzyl
catalytic center. This new material Hf-NU-1000-ZrBn is fully characterized
by a variety of spectroscopic techniques and DFT computation. Hf-NU-1000-ZrBn
is found to be a promising single-component catalyst (i.e., not requiring
a catalyst/activator) for ethylene and stereoregular 1-hexene polymerization
