ABSTRACT

Metallogels belong to a class of molecular materials in which metal ions are diversely involved in the construction of and interaction with self‐assembled networks to provide gel‐phase materials exhibiting switchable functions in response to thermal, mechanical, chemical, photochemical, and electrochemical stimuli. Introduction of metal centers into molecular gels imparts them with optical, electronic, magnetic, and catalytic properties desirable for advanced applications in catalysis, sensing, and optoelectronics. This contribution describes the main experimental techniques useful to characterize the structure and properties of metallogels, and focuses on a particular class of metallogelators that promote metal–metal interactions as a driving force for self‐organization and gel formation.
