The Multifaceted Role of Methylaluminoxane in Metallocene-Based Olefin Polymerization Catalysis
Macromolecules, 2018 In single-site olefin polymerization catalysis, a large excess of cocatalyst is often required for the generation of highly active catalysts, but the reason for this is unclear.

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes
Chemistry – A European Journal, EarlyView.Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.

Heterobimetallic Janus Catalysts for the One‐Pot Synthesis of Polar‐Apolar Block Copolymers
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.Heterobimetallic Janus catalysts act as bifunctional initiators, combining two distinct polymerisation mechanisms in one pot to deliver well‐defined apolar‐polar block copolymers. Combining Earth abundant Ti and Al catalysts for respective α‐olefin and lactone polymerisation, the orthogonal activity is enabled by unprecedented initiation from a Ti ...

Effect of group 5–10 transition metallocenes on polybenzoxazine pyrolysis
Carbon TrendsPolymeric carbon precursors typically yield poorly ordered sp² hybridized carbon after pyrolysis at 1000 °C. This poor ordering results in a turbostratic carbon that lacks the thermomechanical properties of the carbon produced from more graphitizable ...

Controlled spin switching in a metallocene molecular junction
Nature Communications, 2017 The active control of a molecular spin represents one of the main challenges in molecular spintronics. Up to now spin manipulation has been achieved through the modification of the molecular structure either by chemical doping or by external stimuli ...
