Abstract :The protic ionic liquids insert ignore into journalissuearticles values(PILs); insert ignore into journalissuearticles values( 3a-3d ); were synthesized from the reactions of tetraamino-4-insert ignore into journalissuearticles values(fluorobenzyl);spiroinsert ignore into journalissuearticles values(N/O);cyclotriphosphazenes insert ignore into journalissuearticles values( 2a-2d ); with the gentisic acid in THF. The structures of the PILs were verified by elemental analyses, Fourier transform infrared insert ignore into journalissuearticles values(FTIR);, 1 H, 13 C { 1 H} and 31 P { 1 H} NMR techniques. The thermal properties of the PILs were evaluated using TG/DTG/DTA instrument. On the other hand, the antimicrobial activities of the PILs were examined against some bacteria and fungi, and the obtained results were compared with the evaluations of the corresponding fully substituted cyclotriphosphazene bases. The interactions between the PILs and supercoiled PBR322 DNA were also scrutinized, and it was determined that they exhibited significant conformational changes.
