Inspired by the tetracationic “Texas-sized” molecular box, a neutral analogue containing four iodotriazole halogen bond-promoting subunits (“Ibox”) was synthesized. This new macrocycle was prepared by means of azide-alkyne click chemistry....
We describe here a comparative study between two tripodal anion receptor based on selenophene as binding motif, the receptors use benzene or perfluorobenzene as spacer. The presence of the electron-withdrawing...
Hydrostatic pressure can control interactions of chiral countercations with helical receptors containing anions, causing remarkable chiroptical changes.
We highlight a convenient synthesis to selectively deuterate an aryl C–H hydrogen bond donor in a supramolecular anion receptor and use competitive titrations to study the deuterium equilibrium isotope effects (DEIE) in binding HS−, Cl−, and Br−.
The synthesis and evaluation of a new anion receptor based on the 4-amido-1,8-naphthalimide scaffold is described. The findings indicate that the amide N-H is an enhanced H-bond donor but is...
