Chameleonic Cages: Encapsulation of Anionic, Neutral, and Cationic Guest Species within [Fe₄L₄]⁸⁺ Tetrahedral Cages Synthesised from the tris(4-aminophenyl)phosphate pro-Ligand.

ABSTRACT: An adaptable Fe(II) tetrahedral cage, [Fe₄L₄][BF₄]₈ (L=tris(4-(((E)-pyridin-2-ylmethylene)amino)phenyl) phosphate), has been synthesised via self-assembly. By modulating the orientation of its pendant P=O groups, the cage was found to be capable of encapsulating anionic, neutral, and cationic guests, which were confirmed in the solid state via single-crystal X-ray diffraction (SCXRD) and in solution by high-resolution mass spectroscopy (HR-MS), as well as by NMR (¹H, ¹⁹F, ³¹P) studies where possible.
