Self‐Assembly of a Supramolecular, Three‐Dimensional, Spoked, Bicycle‐like Wheel

Abstract

Where there's a wheel, there's a way: The terpyridine-based title system has been synthesized through a facile self-assembly process. Two tris(terpyridine) ligands possessing angles of either 120° or 60° between adjacent tpy units were mixed with a stoichiometric amount of Zn(2+) (2:6:12) to generate the desired coordination-driven bicycle-like wheel (90 % yield).

Engineering 2D→2D parallel interpenetration using long alkoxy-chain substituents

“…An alternative strategy for increasing the dimensionality of the coordination architecture is to design multitopic 4,2':6',4''-tpy ligands. However, despite the successful use of polytopic 2,2':6',2''-tpy ligands for the construction of multinuclear assemblies [22][23][24][25][26][27] or for enhancing electronic communication between metal centres [28,29], little attention has been paid to the coordination potential of multitopic 4,2':6',4''-tpys [30][31][32][33].

Coordination-Driven, Self-Assembly of a Polycyclic, Terpyridine-Based Nanobelt

“…-tpy[ (tpy = [2,2 0 :6 0 ,2 00 ]terpyridine and M = Ru, Fe, Zn or Cd) connectivity to fabricate supramacromolecules has distinct advantages due to the diversity of metal coordination, unique metal-ligand physical properties, rigidity, and ability to incorporate predesigned, structured directionality. Recently, this building protocol has led to the creation of several 2D-and 3D-nano-structures, including bowtie-, butterfly-, and spoke wheel-shaped supramolecules [16][17][18][19]. As well, the porphyrin analogues of [n]cycloparaphenylenes are known [7d].…”

Metallosupramolecular architectures exhibit useful functions for example, gas storage, [11a, b] catalysis, [12] magnetic, [13] self-healing, [14] electrochemical, [15] electrochromic, [16] and electro-rheological [17] properties.Coordinationp olymers, based on different N-atom heterocycles, such as pyridines,including polytopic ligandsand their interactions with metal salts have been presented by Constable, [15a, 18] Kurth, [16a, 19] Newkome, [20] Stuart, [11d] Rowan, [14b, 21] and Schubert. Here, we present the kinetics of growth of MEPEs.T he species in solutionsa re analyzed by light scattering, viscometry and cryogenic transmission electron microscopy (cryo-TEM).
