This work leads not only to potentially useful receptors for such targets as drugs and toxins but also to insights into the role of different binding interactions in molecular recognition.

,Molecular Tweezers: Synthetic Receptors for π-Sandwich Complexation of Aromatic Substrates, receptor has been shown to form a very stable inclusion complex with 9- propyladenine in chloroform solution. Spectroscopic data and studies with adenine analogues suggest a complex containing two hydrogen bonds from the receptor to N-6 and N-7 of adenine and π-stacking interactions between the tweezer and the nucleotide base.

,Molecular Tweezers: Synthetic Receptors for π-Sandwich Complexation of Aromatic Substrates,are shown to form very stable “sandwich complexes” with π-deficient aromatic substrates in organic solvents. The second π-stacking interaction plays a critical role in the complexation - analogous mono-chromophores bind only very weakly. Some of the electronic and structural features required for hi
