Cobalt–Oxygen Bond Homolysis in the Bench‐Stable (Salen*)Cobalt(III) Acetate Complex: Insight into the Organometallic Mediated Radical Polymerization of Diverse Monomers

Macromolecular Chemistry and Physics, EarlyView.
The air‐stable [(Salen*)Co(OAc)] complex initiates the radical polymerization of vinyl monomers via Co–O bond homolysis, distinguishing it from classical air‐sensitive cobalt complexes relying on Co‐C bond cleavage. Accordingly, MMA polymerization proceeds via catalytic chain‐transfer while MA undergoes controlled OMRP involving two distinct initiation

4D Printing of Thermoresponsive OEGMA‐Based Hydrogels with Tunable Response

Macromolecular Materials and Engineering, EarlyView.
This publication introduces a 4D microprinting approach using thermoresponsive POEGMA‐based copolymers. A library of prepolymers is synthesized and characterized with tunable lower critical solution temperatures (LCSTs) between 33 and 66 °C, formulate inks for two‐photon laser printing and fabricate complex microstructures.

From ab initio quantum mechanics to molecular neurobiology: A cation-pi binding site in the nicotinic receptor [PDF]

, 1998
The nicotinic acetylcholine receptor is the prototype ligand-gated ion channel. A number of aromatic amino acids have been identified as contributing to the agonist binding site, suggesting that cation-pi interactions may be involved in binding the ...

Data in support of dual-functionalized cellulose nanofibrils prepared through TEMPO-mediated oxidation and surface-initiated ATRP

Data in Brief, 2015
We previously studied a suitably 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (TOCNs) that can be further functionalized with initiating sites and overcame the obstacle of performing atom transfer radical polymerization ...
