The dicationic styrylimidazo[1,2-a]pyridinium dyes were synthesized and characterized using 1H NMR, 13C NMR, mass spectral techniques and elemental analysis. In addition, their photophysical and DNA-binding properties were investigated. The dyes absorb in the UV region with maxima at 342–358 nm, and the emission spectra of these derivatives show a maximum at 409–475 nm with moderate Stokes shift....
