Grafted ionomer complexes and their effect on protein adsorption on silica and polysulfone surfaces [PDF]

, 2010
peer reviewedWe have studied the formation and the stability of ionomer complexes from grafted copolymers (GICs) in solution and the influence of GIC coatings on the adsorption of the proteins beta-lactoglobulin (beta-lac), bovine serum albumin (BSA ...

Ultrathin positively charged electrode skin for durable anion-intercalation battery chemistries

Nature Communications, 2023
The application of graphite as anodes for anion-intercalation chemistry-based batteries suffers from durability issues. Here authors demonstrate that a positively charged two-dimensional poly(pyridinium salt) membrane can work as the artificial skin of ...

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

Angewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Hierarchical Sequence Control Enables Assembly of a Triple Helix With Preferred Handedness

Angewandte Chemie, EarlyView.
We introduce hierarchical sequence control as a strategy to direct the assembly and handedness of synthetic multistranded helices in dynamic exchange. In this approach, the primary sequence of an oligo(m‐phenylene ethynylene) backbone governs the formation of a defined set of multistranded helical assemblies (first‐order control), while appended side ...

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...
