Information on the structure and dynamics of condensed forms of DNA is important in understanding both natural situations such as DNA packaging and artificial systems such as gene delivery complexes. We have established the fluorescence of bisintercalator 1,1'-(4,4,8,8-tetramethyl-4,8-diazaundecamethylene)bis[4-[[3-methylbenz-1,3-oxazol-2-yl]methylidine]-1,4-dihydroquinolinium] tetraiodide (YOYO-1)
