POSS-based supramolecular amphiphilic zwitterionic complexes for drug delivery

A novel POSS-based supramolecular amphiphilic zwitterionic polymer exhibited excellent stability in both extracellular and intracellular pH environments and well encapsulated the antitumor drug DOX, and has the potential to improve smart drug delivery and enhance antitumor efficacy for biomedical applications.

Penta- and hexaorganostannate(iv) complexes based on O-heterocyclic ligands

Novel hypercoordinate, pure heteroaryl substituted organotin(iv) compounds have been explored, which appeared either as intramolecularly stabilized zwitterionic complexes or solvent separated cation/anion pairs.

Novel zwitterionic complexes arising from the coordination of an ambiphilic phosphorus–aluminum ligand to gold

Upon coordination of Mes2PC(CHPh)AltBu2, bridging P→M–Cl→Al coordination was observed with Rh and Pd fragments, while chloride abstraction occurred with Au. The resulting zwitterionic complexes have been fully characterized and analyzed by DFT calculations.

Synthesis and dynamic behaviour of zwitterionic [M(η6-C6H5-BPh3)(coe)2] (M = Rh, Ir) cyclooctene complexes

Hindered rotation about the metal–cyclooctene bond in bis-cyclooctene zwitterionic complexes results in an unusual equilibrium between two rotational isomers.
