Abstract

The protic
ionic liquids (PILs) (3a-3d) were
synthesized from the reactions of tetraamino-4-(fluorobenzyl)spiro(N/O)cyclotriphosphazenes (2a-2d) with the gentisic acid in THF. The
structures of the PILs were verified by elemental analyses, Fourier transform infrared (FTIR), ¹H, ¹³C
{¹H} and ³¹P {¹H} 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.

Keywords
