Impact of Oxygen and Sulfur Heteroatom Core Substitution on Catalyst Properties of Phenoxazines and Their Performance in Organocatalyzed Atom Transfer Radical Polymerization (O‐ATRP)

Chemistry – A European Journal, EarlyView.
Phenoxazine core structural modification reveals the impact of charge transfer on stronger excited state reduction potentials. We observed that modifying the core of a photocatalyst that does not exhibit charge transfer yields a highly reducing singlet excited state reduction potential compared to a charge transfer equivalent. Abstract Phenoxazines are

Continuous Flow Block Copolymer Nanoaggregate Synthesis and Their Flow Dialysis Purification

Chemistry–Methods, EarlyView.
This work details the methodology for the synthesis of block copolymer nanoparticles through continuous flow self‐assembly and purification via flow dialysis. Nanoaggregates are formed by mixing block copolymer solutions in THF with water, followed by dialysis to eliminate excess solvent.
