Novel bifunctional acridine-acridinium conjugates: Synthesis and study of their chromophore-selective electron-transfer and DNA-binding properties

A novel bifunctional acridine-acridinium conjugates with varying polymethylene spacer groups were synthesized and their DNA interactions were investigated using various biophysical techniques. The results demonstrate that these novel water-soluble system that exhibit quantitative fluorescence yields, chromophore-selective electron transfer.
