Supramolecular pyridyl urea gels as soft matter with antibacterial properties against MRSA and/or E-coli

The synthesis and characterisation of novel aryl-pyridyl ureas are described, which form self-assembly structures via extended hydrogen bonding and pi-pi interactions in the solid state, and in selected cases, form supramolecular gels with antimicrobial properties against Staphylococcus aureus and/or Escherichia coli.
