Supramolecular chemistry of metal complexes in solution

Abstract

Building on established supramolecular chemistry, metal coordination and organometallic chemistry have been widely explored for supramolecular polymers and nanostructures. Increasingly, research has demonstrated that this approach is promising for the synthesis of novel materials with functions and properties derived from metal elements and their coordination structures. Unique self-assembling behaviour and unexpected supramolecular structures are frequently discovered due to multiple non-covalent interactions in addition to metal coordination. However, an explicit understanding of the synergistic effects of non-covalent interactions for designed synthesis of metal containing assemblies with structure correlated properties remains a challenge to be addressed. Recent literature in the area is highlighted in this review in order to illustrate newly explored concepts and stress the importance of developing well understood and controlled supramolecular chemistry for designed synthesis.

A σ-hole interaction with radical species as electron donors: does single-electron tetrel bonding exist?

“…60 In the present study, we found that the synergistic effect involved with single-electron tetrel bonds is also non-negligible. 60 In the present study, we found that the synergistic effect involved with single-electron tetrel bonds is also non-negligible.…”

Control over the Self‐Assembly Modes of PtII Complexes by Alkyl Chain Variation: From Slipped to Parallel π‐Stacks

“…[21][22][23][24][25][26][27][28][29][30] These systems have a strong propensity to aggregate in solution and in the solid state via Pt•••Pt and/or other secondary forces, as recently shown for various classes of complexes in a comprehensive review by Yam and co-workers. 31 Among them, the self-assembly features of hydrophobic Pt(II) complexes with acetylide, [32][33][34][35][36] bidentate, [37][38][39] tridentate N-donor, [40][41][42] and cyclometalating ligands [43][44][45] are relatively well understood.…”

Multifarious facets of sugar-derived molecular gels: molecular features, mechanisms of self-assembly and emerging applications

“…Extensive research efforts towards the evolution of novel properties utilizing the underlying principles of self-assembly (i.e., hydrogen bonding, p-p stacking, solvophobic effects, van der Waals forces, charge-transfer interactions and metal-ligand coordination) as a key route has led to the generation of a vast area of research known as supramolecular chemistry. 43 Diverse molecular building blocks derived from long chain hydrocarbons or steroid derivatives, [44][45][46][47][48] amino acid derivatives, [49][50][51][52][53][54] urea, 55 carbohydrate-derived systems, 56 metal complexes, [57][58][59][60][61] charge-transfer complexes, 62,63 macrocycles 64,65 and organic salts 66,67 have been used to synthesize low molecular-weight organogelators (LMOGs) as well as hydrogelators (LMHGs). In the course of sol-to-gel transitions, the transcription of intrinsic molecular features from the molecular level to complex supramolecular structures occurs.…”
