Water soluble polycationic arene host systems have been prepared, using DABCO as the source of the cationic charge, in which the arene group is complexed to chromium tricarbonyl. Association constants for two salts were determined by NMR methods and the role of IR carbonyl band of the Cr(CO)3 moeity as reporter group explored. The different properties of the salts in the solid state, in water and, where possible, organic solvents were examined and it was found that the nature of the anion had no effect on the carbonyl IR band in water, although it did in the solid state.
