Synthesis of dinuclear pyridyl-amido hafnium and zirconium complexes toward olefin polymerization with unexpected stereospecificity and ultra-high molecular weight capability

A bifunctional pyridyl-imine ligand (syn-L) bridged by the rigid anthracene has been developed to support dinuclear Hf and Zr metal complexes (syn-M2; M = Hf or Zr). syn-Hf2 only exists...
