Metal Coordination To Assist Molecular Gelation

“…[14] Catalytic metallogels represent a promising approach in supramolecular catalysis. [15] Binding of the paramagnetic metal ion Gd III to the tetraazamacrocyclic moiety of a gelling peptidic scaffold led to biocompatible supramolecular structures that are useful for clinical and biological applications based on magnetic resonance imaging. [16] Counteranion exchange was elegantly used to control the conformation of Ag I -containing coordination polymers in water, and, thereby, the sol-gel transition.…”

A Favorable, Narrow, δh Hansen‐Parameter Domain for Gelation of Low‐Molecular‐Weight Amino Acid Derivatives

“…[6] This trend is justified by the fact that the intriguing properties of gels allow the use of these supramolecular materials in various areas of chemistry and biology, such as sensors, [9] drug-delivery agents, [10] biomimetics, [11] and in the field of catalysis. [12] They can also be used to improve mechanical properties of soft solids. [13] A preliminary analysis shows that the structures of LMWGs can be of different natures.…”

Novel Organometallic Gelators with Enhanced Amphiphilic Character: Structure−Property Correlations, Principles for Design, and Diversity of Gelation

“…Incorporation of a metal moiety into LMMGs is expected to result in even more attractive organometallic and coordinatively bound gelators (LMMGs), offering additional functionalities due to the variation of the oxidation state, the coordination geometry, and the coligand sphere provided by the metal center . To this rapidly growing field, we have contributed organometallic gels based on sugar chromium carbenes, functionalized titanocenes, and most recently CNC pincer biscarbene palladium gelators, which exhibit catalytic activity in the gel state. Due to their Lewis acidity, the titanocene derivatives are able to form gels with a large variety of polar and apolar solvents.…”
