A novel pentiptycene-based bis(crown ether) host incorporating two dibenzo-24-crown-8 ether moieties has been synthesized, and its efficient complexation ability toward cyclobis(paraquat-p-phenylene) in solution and in the solid state has been explored.

Triptycene-based macrotricyclic host containing two dibenzo-30-crown-10 moieties could form ladder-like supramolecular poly[3]pseudorotaxanes with π-extended viologens in both high concentration solution and solid state.

We describe the synthesis of a diphenylglycoluril/dibenzo-crown-6 molecular chalice, the self-assembly at the air/water interface and its complexation properties in solution and at the water/chloroform interface.

The syntheses of two functionalized xanthenes are described which after deprotonation represent ligands for dinuclear metal complexes. For the previously prepared [Xanthdim]H2 – which after deprotonation leads to a ligand with two adjacent β -diiminato binding sites – a significantly improved synthetic procedure is described involving the Pd catalyzed coupling of two diethyl malonate moieties t...

Carbamazepine (CBZ) is well known as a model active pharmaceutical ingredient used in the study of polymorphism and the generation and comparison of cocrystal forms. The pharmaceutical amide dihydrocarbamazepine (DCBZ) is a less well known material and is largely of interest here as a structural congener of CBZ. Reaction of DCBZ with strong acids results in protonation of the amide functionalit...
