Metal Polyphenol Network Enables Photo‐ATRP Under Blue Light
Macromolecular Rapid Communications, EarlyView.A new ligand for light‐mediated ATRP derived from a model polyphenol was modified via a Mannich reaction to form a complex with an iron‐based photocatalyst. Experiments confirmed the formation of chain‐extendable macroinitiators, as well as fractions of polymers incapable of chain extension.

A novel n‐type dimer dopant for semiconducting polymers
Polymer International, EarlyView.A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.

High performance liquid chromatography for direct and indirect enantiomeric separations of chiral drugs [PDF]
, 1992 This thesis deals with some analytical and pharmaceutical problems associated with chiral drugs. Although there can be marked differences between enantiomers in their pharmacological profile, many chiral drugs are still marketed as racemic mixtures.

Enhanced Degradation of Vinyl Copolymers Based on Lipoic Acid
Journal of Polymer Science, Volume 63, Issue 6, Page 1345-1351, 15 March 2025.ABSTRACT The introduction of degradable units into the backbone of commodity vinyl polymers represents a major opportunity to address the societal challenge of plastic waste and polymer recycling. Previously, we reported the facile copolymerization of α‐lipoic acid derivatives containing 1,2‐dithiolane rings with vinyl monomers leading to the ...
