Helical Alleno-Acetylenic Oligomers with High Chiroptical Activity

The principal goal of this project is to develop new supramolecular helical cages ("helicages"), based on enantiopure alleno acetylenic ligands. We recently found that these helicages feature an interior cavity shaped by the lean alleno-acetylenic backbones, and various small cyclic guests form inclusion complexes with high selectivity. The intrinsically strong Cotton effect of alleno-acetylenes combined with exciton coupling allows for the chiroptical detection of nonchromophoric, achiral guests in a highly selective manner. Particularly high affinity towards 1,4-dioxane enabled its selective detection at ppm (parts per million) levels. We are currently extending the triple-helicates to systems containing multiple cavity binding sites and will investigate allosteric effects on guest recognition at these sites.
