Imidazolium tagged acridines: Synthesis, characterization and applications in DNA binding and anti-microbial activities

• New water soluble luminescent 4,5-bis imidazolium tagged acridines were synthesized.
• CT-DNA binding study of acridine derivatives was demonstrated.
• Anti-bacterial and anti-fungal activities of acridine salt were tested.

New water soluble 4,5-bis imidazolium tagged acridines have been synthesized and structurally characterized by multinuclear NMR and single crystal X-ray diffraction techniques. The DNA binding and anti-microbial activities of these acridine derivatives were investigated by fluorescence and far-UV circular dichroism studies.
