ATP and triphosphate anions complexation by bis-linear tetraamines: Strong interactions at neutral pH

The study of host-guest binding interaction involving two bis-linear tetraamines with triphosphate and ATP highlights the different coordination schemes exhibited by these anions according to their inorganic or organic nature. In particular, concerning ATP, the role of the aromatic linker through π-stacking interactions with the adenine part of the nucleotide, is evidenced.
