Block copolymers form the basis of the most ubiquitous materials such as thermoplastic
elastomers, bridge interphases in polymer blends, and are fundamental for the development …

Precise control over product structure is the goal of all chemical synthesis. In the field of
polymer synthesis, the structure of the resultant macromolecule is intimately linked to its …

A series of tetradentate amine (bisphenolate) ligands have been synthesized and
complexed to Ti (IV), Zr (IV), and Hf (IV) centers. Two distinct ligand sets have been …

The opening up of new markets, particularly in the Far East, is expected to increase the
industrial demand for more (and new) plastic materials. In turn, this will drive the need for …

Aiming at higher activities of group IV diamine bis (phenolate) catalysts in olefin
polymerization, ligands containing electron-withdrawing groups have been introduced. The …

A series of novel Ti (IV) complexes bearing new type of nonsymmetric amine-bis (phenolate)
tetradentate ligands, Me2NCH2CH2N [2-O-3-R1-5-t BuC6H2][CH2 (2-O-3-R2-5-t BuC6H2)] …

A family of 17 iron (III) aminobis (phenolate) complexes possessing different phenolate
substituents, coordination geometries, and donor arrangements were used as catalysts for …

A tactical approach: C3-chiral ancillary ligands such as tris (oxazolinyl) ethane allow
stereocontrol in olefin polymerization (see scheme). An alkyl ScIII catalyst polymerizes 1 …

Aminobisphenols with side-arm donors are versatile tetradentate ligands that effectively
coordinate to the metal ions in a tripodal fashion. Most of the metal ions form electrically …

New groups 3 and 4 organometallic and coordination compounds supported by the
tetradentate diamino-bis (phenolate) ligands O2tBuNN 'and O2MeNN 'are reported …
