The inverse quadrupolar moments of the phenyl and pentafluorophenyl residues in the base pair P-F5 promotes strong intramolecular stacking interactions in DNA duplexes. The more natural base pairs are replaced by this novel pair the higher the thermodynamic stability of the resulting duplex if they are arranged in an alternating fashion.
