Preparation and properties of DNA-lipid complexes carrying pyrene and anthracene moieties

Novel DNA-lipid complexes carrying pyrene and anthracene were prepared by substituting sodium counter cations with cationic amphiphilic lipids, namely lipid(PY) and lipid(Anth), in which the actual mole ratios of phosphate to lipid were 1:1.11 and 1:1.03, respectively. DNA-lipid(PY) and DNA-lipid(Anth) complexes were soluble in common organic solvents. The solution of DNA-lipid(PY) and DNA-lipid(Anth) complexes emitted fluorescence in 27.8 and 45.4% quantum yields.
