Tetradentate halogen bonding macrocyclic anion receptor inspired by the “Texas-sized” molecular box

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....

Host-guest complexes vs supramolecular polymers in chalcogen bonding receptors: experimental and theoretical study

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...

Ground- and excited-state dynamic control of an anion receptor by hydrostatic pressure

Hydrostatic pressure can control interactions of chiral countercations with helical receptors containing anions, causing remarkable chiroptical changes.

Deuterium equilibrium isotope effects in a supramolecular receptor for the hydrochalcogenide and halide anions

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−.

Comparing the anion binding of 4-amido- with 4-amino-1,8-naphthalimides

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...

Design and property investigation on a five-interaction-based fluorescent anion receptor clip

A new generation of anion acceptor is designed from three key structural fragments and five simultaneous non-covalent interactions.
