Connectivity and topology invariance in self-assembled and halogen-bonded anionic (6,3)-networks [PDF]

, 2018
open5noWe report here that the halogen bond driven self-assembly of 1,3,5-trifluorotriiodobenzene with tetraethylammonium and -phosphonium bromides affords 1:1 co-crystals, wherein the mutual induced fit of the triiodobenzene derivative and the bromide ...

Sulfonium‐Based Antimicrobial Block Copolymers: Influence of Hydrophobicity on Biological Activity and Antibiotic Synergy

Macromolecular Rapid Communications, EarlyView.
Sulfonium‐based antimicrobial block copolymers combine an active cationic hydrophobic block with a neutral hydrophilic block to improve cytocompatibility. The hydrophobicity of the sulfonium‐based block controls the activity against S. aureus and E coli.

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

ChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

Journal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...
