Synthesis and binding or permethylated diamondoid ammonium salts

Supramolecular complexes are stabilized by non-covalent interactions between the host and the guest molecule. Molecular recognition studies can give insight into many processes occurring in nature and prove useful for technological applications. It was recently demonstrated that functionalized adamantane and diamantane ammonium salts are suitable guests for cucurbituril hosts. Moreover, some diamantane derivatives are capable of extremely tight binding with cucurbiturils in water, forming complexes with attomolar dissociation constants. Such ultrastable complexes rival the strength of binding processes acting in biomolecular receptors (e.g., avidin-biotin). As a continuation of our research, we explored complexation of selected adamantane and diamantane ammonium salts with cyclodextrin host molecules. The binding strength was assessed as a function of diamondoid salt size, functional group position and cyclodextrin cavity size. By changing these parameters, a structure-selectivity relationship can be determined and next generation of guests proposed. Various NMR spectroscopic techniques and ITC measurements were employed to determine the stability constants and explore host-guest interactions. Computation methods were used to gain further insight into structural features of formed complexes and to better understand the factors governing their stabilities.
