A pyridinium dye with N-butyl-carbazole as an electron donor group and pyridinium cation as electron acceptor group has been synthesized. The crystal structure and photophysical properties of the dye in different solvents are researched. The interaction between the dye and DNA is also researched. The results reveal that the dye can be used as a DNA probe.
