Halogen-bond-driven supramolecular assemblies of quaternary-ammonium-iodide-containing polymers in three phases

Rational design of supramolecular chirality in porphyrin assemblies: the halogen bond case.

Asymmetric functionalization of the tetraarylporphyrin scaffold, combined with directional supramolecular halogen bonding, yields chiral architectures.

Facile synthesis and supramolecular chemistry of hydrogen bond/halogen bond-driven multi-tasking tectons.

Hydrogen bonds and halogen bonds can be used as synthetic vectors without structural interference as long as the primary molecular recognition events are designed around a careful combination of geometric and electrostatic complementarity. In addition, a one-step procedure for the synthesis of tectons equipped with powerful hydrogen- and halogen-bond donors is presented.

Formation of Supramolecular Polymers from Homoditopic Molecules Containing Secondary Ammonium Ion and Crown Ether Moieties

Antibacterial activity of bone cement containing quaternary ammonium polyethyleneimine nanoparticles.

Sir, A bone cement mantle is commonly used in orthopaedic surgery, and creates an ideal environment for bacterial growth. Bacterial infection following joint replacement surgery is a catastrophic complication. It is estimated that infections occur in up to about 2% of primary hip and knee replacements, whereas revision surgery carries a 2–3-fold higher risk. The most common bacteria isolated fr...
