Orthogonal, modular anion–cation and cation–anion self-assembly using pre-programmed anion binding sites

Abstract

Subcomponent self-assembly relies on cation coordination whereas the roles of anions, often only emerging during self-assembly, are growing. When sites for anions are instead pre-programmed, they have the potential to...

The Dynamic Chemistry of Orthoesters and Trialkoxysilanes: Making Supramolecular Hosts Adaptive, Fluxional, and Degradable

“…Our dual-assembly reaction (in chloroform/DMSO 5:1) therefore represents a rare example where the binding of Cl – both outcompetes and enables the binding of Cs + . A related “modular” self-assembly concept has recently been utilized by Flood and co-workers …”

Transient and elusive intermediate states in self‐assembly processes: An overview

“…The electrocatalytic self-assembly of molybdenum blue clusters [164] was investigated to emphasize the formation of intermediates and the role of specific precursors. Dhara et al [165] strategically analyze formation intermediates in the self-assembly of multi-ion systems, utilizing pre-programmed anion and cation binding sites to guide the assembly process at the molecular level. These studies showcase diverse aspects of self-assembly processes, highlighting the importance of intermediates in tailoring the properties of resulting metal-organic structures.…”

Steric Control over the Threading of Pyrophosphonates with One or Two Cyanostar Macrocycles during Pseudorotaxane Formation

“…Since the first reports half a century ago, [1–4] the field of supramolecular anion recognition [5,6] and anion receptor chemistry [7–13] has made significant advances. Notable applications [14] of anion recognition include sensing, [15–17] membrane transport, [18,19] catalysis [20–24] and increasingly the self‐assembly of supramolecular architectures [25–34] . Anion recognition has also been used to synthesize mechanically interlocked molecules [35–38] .…”

“…Notable applications [14] of anion recognition include sensing, [15][16][17] membrane transport, [18,19] catalysis [20][21][22][23][24] and increasingly the selfassembly of supramolecular architectures. [25][26][27][28][29][30][31][32][33][34] Anion recognition has also been used to synthesize mechanically interlocked molecules. [35][36][37][38] In most of these interlocked examples, anions play the role of a template, such that the anion is not part of either the thread or the macrocycle and can be removed after synthesis.…”
