The Boc and N,N'-dicyclohexylurea capped γ-amino acid upon monobromination showed phosphorescence in the solid state. The compound exhibited different photoluminescence intensity and lifetimes in crystals obtained from ethyl acetate and methanol. X-ray crystallography revealed that the intermolecular C=O…Br halogen bond directs the heavy atom effect to produce the phosphorescence.

Neutral tetradentate halogen bond donor foldamers were synthesised and exhibit enhanced anion affinities over their hydrogen bonding analogues, displaying iodide selectivity over lighter halide, carboxylate and dihydrogen phosphate anions. A foldamer with a chiral (S)-binaphthol motif was demonstrated to distinguish between enantiomers of chiral anions.

A convenient, effective, and scalable protocol for stabilizing volatile liquid chemicals is reported. Through the use of halogen-bond driven co-crystal synthesis, several examples of liquid iodoperfluoroalkanes are transformed into crystalline materials with low-vapor pressure, considerable thermal stability, and moisture resistance. The target compounds can subsequently be re-generated through...

UNLABELLED The purpose of the study was to compare temperature rise during polymerisation of resin based composites (RBCs) with two LED light curing units (LCUs) compared to a halogen control light. METHODS Forty-five extracted molars, patients aging 11-18 years were used. Thermocouples (TCs) were placed in contact with the roof of the pulp chamber using a 'split-tooth' method. Teeth were pla...

We describe here a method using differential scanning calorimetry (DSC) to determine the energy of biomolecular halogen bonds (X-bonds) in a DNA system. This system is unique because we are able to isolate the energetics of a specific molecular interaction from the thermodynamic properties of an entire system. To achieve this goal, we engineered DNA Holliday junctions that are stabilized by eit...
