Construction of a Highly Symmetric Nanosphere via a One-Pot Reaction of a Tristerpyridine Ligand with Ru(II)

Abstract

A three-dimensional, highly symmetric, terpyridine-based, spherical complex was synthesized via the coordination of four novel, trisdentate ligands and six Ru(2+) ions, and it exhibits excellent stability over a wide range of pH values (1-14). Structural confirmation was obtained by NMR and ESI-TWIM-MS.

Assembled molecular face-rotating polyhedra to transfer chirality from two to three dimensions

“…Most of these polyhedra are highly symmetric and achiral202122232425, and chiral molecular polyhedra with lower symmetry have attracted more and more attention because they increase the complexity of motifs and may bring more sophisticated functions262728293031. Generally, the construction of chiral molecular polyhedra follows two strategies: to use predetermined 3D chiral building blocks as the edges3032, vertices3334 or faces3536 of polyhedra to transfer 3D chirality of the components to the 3D chirality of the chiral structures, or to use achiral components to generate chiral metal-organic polyhedra373839404142 during a self-assembly process. The latter approach relates to symmetry breaking, and investigation of the process of such complex molecular self-assembly may help to elucidate the evolution of matter towards complexity43.…”

Precise Molecular Fission and Fusion: Quantitative Self‐Assembly and Chemistry of a Metallo‐Cuboctahedron

“…[13] Thel inearly coordinated, pseudooctahedral {tpyÀM 2+ Àtpy} complex (tpy = 2,2':6',2''-terpyridine) has been demonstrated to be ag ood option for the fabrication of 2D and 3D supramolecules. [16][17][18] Using 2,2':6',2''-terpyridine as ar eadily available and easily functionalized monomer,w eh ave reported the selfassembly of numerous 2D metallomacrocycles,i ncluding triangles, [19] hexagons, [20] aS ierpiń ski gasket, [21] and, most recently,aSierpiń ski triangle, [22] wherein the vertices were connected through terpyridine-based coordination chemistry ( Figure 1). Building on these mathematically derived shapes, we herein describe the single-step,quantitative self-assembly of 3D,monodisperse metallospheres with adiameter of 6mm, which are based on ac lassic Archimedean solid-the cuboctahedron-one of 13 convex polyhedra exhibiting two or more nonintersecting regular convex polygons arranged such that all sides are of equal length.…”

Star PolyMOCs with Diverse Structures, Dynamics, and Functions by Three‐Component Assembly

“…[9][10][11][12][13][14][15][16][17][18][19][20][21][22] By rational design of the ligands and proper choice of the metal ions, MOCs of different M x L y stoichiometries, sizes, and geometries can be synthesized. [23][24][25][26][27][28][29] Inspired by this structural versatility and potential applications such as mechanical enhancement, catalysis, encapsulation, sensing, etc., much effort has been recently devoted to installing MOCs into polymer networks to provide 'polyMOC' hybrid materials with tunable viscoelasticity and functionality. [30][31][32][33][34][35][36][37] One [30,[38][39][40][41][42] ; however, there is still a great need to understand how polyMOC microstructure translates to bulk material properties such as modulus and relaxation dynamics.…”
