“…Whilst self‐assembly of discrete supramolecular architectures has reached some extraordinary heights in terms of sheer size of assembly product, there are still many open questions regarding how best to develop assemblies that respond to their environment and reversibly switch between assembly states. Along these lines of thought, Rebek has shown that both photochemical switching of an azobenzene guest, or the addition of a second type of assembly subunit, can induce assembly switching in a supramolecular host .…”

Precision Switching in a Discrete Supramolecular Assembly: Alkali Metal Ion‐Carboxylate Selectivities and the Cationic Hofmeister Effect

A cavitand host has been shown to switch from a dimeric assembly to a tetrameric assembly in the presence of cations. Induced by pseudo-specific cation binding attenuating the net negative charge of each host, switching was shown to be highly cation selective. Thus, the concentration of cation required to induce assembly switching ranged from 2 mM in the case of N(n-Bu) to ∼80 mM in the case of Na . Overall cation affinity was found to be essentially the reverse of Collins' law of matching water affinities, which predicts Na to have the strongest affinity for carboxylate groups. Combined with previous data, these results highlight the point that cation affinity for carboxylates are in large part dictated by context.

“…Synthetic supramolecular chemistry focused on the construction of specific and functionalized supramolecular architectures through self‐assembly during the past few decades. Coordination‐driven self‐assembly is one of the most useful methods for preparing multifarious supramolecular structures, such as 1D helicates, 2D macrocycles, knots, links, 3D cages, and capsules . 3D supramolecules with well‐defined cavities are attractive due to their ability of encapsulating guest molecules.…”

Coordination-driven self-assembly as a powerful bottom-up approach has been extensively used to construct multifarious supramolecular architectures with increasing complexity and functionality. Due to the unique cavity structures and precisely controllable dimensions, 3D supramolecules display unprecedented properties and functions in catalysis, sensing, gas storage, and smart materials. Herein, we have built two 3D nanocages with different sizes by changing the length of the organic ligand arms. The structures were characterized by 1D and 2D NMR spectroscopy, electrospray ionization-mass spectrometry (ESI-MS), traveling wave ion mobility-mass spectrometry (TWIM-MS), gradient tandem-mass spectrometry (gMS ), and transmission electron microscopy (TEM). Furthermore, the intermolecular dynamic exchange of two 3D nanocages was conducted to construct a series of hybrid 3D structures as evidenced by mass spectrometry.

“…In this line, synthesis of self‐assembled homoleptic coordination complexes of Pd m L n compositions are quite well‐explored, in which L stands for a non‐chelating bidentate or polydentate ligand. A number of Pd m L 2 m type complexes are prepared using bidentate ligands where the values m are 2, 3, 4, 6, 8 (not isolated), 9, 12, 24, 30, and 48 . Tridentate and tetradentate ligands are less explored in this area; however, the formulae of complexes prepared using the former ligands are Pd 3 L 4 , Pd 6 L 8 , and Pd 18 L 24 whereas the latter type is known to afford Pd 4 L 4 and Pd 24 L 24 type complexes.…”

A pentanuclear coordination complex assembled from any palladium(II) component and non-chelating ligands is hitherto unreported. The pentanuclear complex [Pd (L1) (L2) ](BF ) , 1 reported here was prepared by the spontaneous complexation of [Pd(DMSO) ](BF ) with the non-chelating bidentate ligands 1,4-phenylenebis(methylene) diisonicotinate, L1 and 4,4'-bipyridine, L2 in a one-pot method at room temperature. The planar polycyclic complex 1 with outer diameters of ≈3 nm is termed as a "molecular star" owing to its resemblance with a pentagram shape. Interim paths leading to the star were also probed to decipher related dynamics of the system.
