Binding of nucleotides in water by phenanthridinium bis(intercaland) receptor molecules

Abstract

The bis(phenanthridinium) receptor molecules 3–5 bind nucleotides in aqueous media by stacking interactions between cis-oriented receptor units and the intercalated nucleic base part of a nucleotide with stability constants in the range 105–106 dm3 mol–1, the highest measured to date for these type of receptors and substrates.
