Interactions between acyclic CB[]-type receptors and nitrated explosive materials

The binding ability of acyclic CB[ n ]-type receptors M1 , M2 and macrocyclic CB[7] toward explosive materials was investigated. Acyclic M2 demonstrates an overall better binding and solubilizing ability, and lower fluorescence in the presence of aromatic explosive compounds, suggesting its future application for the detection of harmful explosive materials. This communication studies the binding properties of acyclic CB[ n ]-type receptors toward nitrated explosive materials.
