Notes

Abstract: The polarities of ethylammonium nitrate (EAN), propylammonium nitrate (PAN) and tributylammonium nitrate (TBAN) are reported based on the photophysical properties of benzo[ghi]perylene dissolved in the liquid organic salts. Numerical BPe values, calculated as the ratio of the emission intensities for bands l and III (BPe = I/III), range from 1.20 for both EAN and PAN to 1.36 for TBAN. These results, combined with the BPe values obtained in an earlier study, suggest that the three liquid organic salts might show similar behaviour to acetonitrile, N,N-dimethylacetamide, N,N-dimethylformamide and dimethyl sulphoxide in terms of their molecular interactions with polycyclic aromatic hydrocarbon solutes.
