Design of aD_3h-symmetry prismatic tris-(ferrocene-1,1′-diyl) molecular cage bearing boronate ester linkages

Abstract

A D3h-symmetry prismatic tris-(ferrocene-1,1′-diyl) molecular cage has been synthesized and characterized, and the mechanism behind its synthesis has been studied with DFT methods.

Ferrocene-Derived Palladium(II)-Based Metallosupramolecular Structures: Synthesis, Guest Interaction, and Stimulus-Responsiveness Studies

“…14,15 As such, there has been substantial research into stimulus-responsive homo-and heteroleptic metallosupramolecular architectures that respond to changes in pH, 16−21 redox processes, 22,23 solvent, 24 light irradiation, 25−27 and addition of competing metals, ligands, or guests. 28−30 Ferrocene (Fc) has been investigated as a building block in supramolecular and metallosupramolecular structures 31,32 and polymers and machines. 33−37 The structural flexibility of Fc, such as rotation and tilting that is facilitated by the cyclopentadienyl (Cp) rings about the Fe II center, 38,39 generates a range of possible conformations for 1,1′-difunctionalized derivatives.…”
