In the present study, the condensation reaction of N3P3Cl6 (1) with sodium 3-(4-fluorobenzylamino)-1-propanoxide gave partly substituted 4-fluorobenzylspiro cyclotriphosphazene (2). The Cl replacement reactions of 2 with excess benzylamine, n-hexylamine, n-buthylamine and n-propylamine led to the formation of the corresponding 4-fluorobenzylspiro(N/O)tetrabenzylamino (3a), tetrahexylamino (3b), tetrabuthylamino (3c) and tetrapropylamino (3d) cyclotriphosphazenes. The protic ionic liquids (PILs), phosphazenium salts (4a-4d), were obtained from the reactions of the corresponding phosphazene bases (3a-3d) with gentisic acid in dry THF. The structures of all the isolated cyclotriphosphazene derivatives were determined by elemental analyses, FTIR and 1H, 13C{1H}, 31P{1H} NMR techniques. The crystal structure of 4d was verified by X-ray diffraction analysis. All the compounds were screened for antibacterial and antifungal activities against bacteria and yeast strains. The interactions of the compounds with supercoiled pUC18 plasmid DNA were investigated.
