“…14). 39 When a hydrogel covalently functionalised with ferrocene groups was immersed in an aqueous solution of anionic pillar[6]arene H2 , the hydrogel swelled dramatically, with an approximately 11-fold increase in weight compared with that in pure water constructed from the cationic pillar[5]arenes Multilayer films were obtained by repeating these alternating immersion steps. This swelling was due to the formation of inclusion complexes between anionic pillar[6]arene H2 and the ferrocene groups in the hydrogel.…”

This tutorial review summarizes the continuining exploration of three prominent water-soluble hosts: cucurbiturils, pillar[n]arenes and deep-cavity cavitands. As we describe, these hosts are revealing how orchestrating the Hydrophobic Effect can lead to a broad range of properties and applications, from: nano-reactors, supramolecular polymers, stimuli-responsive biointerfaces, switches, and novel purification devices. We also describe how their study is also revealing more details about the properties of water and aqueous solutions.

“…Metallopolymers containing ferrocene units have been applied for redox‐triggered release of a dye from patchy nanocapsules, for switching of surface wettability, in memory devices, and for permselective membrane gating . A good number of reported polymers are water‐soluble as a result of the introduction of PEG or polyelectrolyte blocks , , , , …”

The appearance of ferrocene in the middle of the 20th century has revolutionized organometallic chemistry and is now providing applications in areas as varied and sometimes initially unexpected as optical and redox devices, battery and other materials, sensing, catalysis, including asymmetric and enantioselective catalysis, and medicine. The author presents here a general, although personal, view of ferrocene's chemistry, properties, functions, and applications through a literature survey involving both historical and up‐to‐date trends and including examples of his group's research in a number of these areas. The review gathers together general features of ferrocene chemistry and representative examples of the salient aspects. Its focus is on ferrocene's basic properties, ferrocene‐containing ligands, the ferrocene/ferricinium redox couple, ferrocene mixed‐valence and average‐valence systems, the ferricinium/ferrocene redox shuttle in catalysis, ligand‐exchange reactions, ferrocene‐containing polymers, ferrocene‐containing structures for cathodic battery and other materials, ferrocenes in supramolecular ensembles, liquid crystals, and nonlinear optical materials, ferrocene‐containing stars and their electrostatic effects, ferrocene‐containing dendrons, dendrimers, and nanoparticles (NPs) and their application in redox sensing and catalysis, and ferrocenes in nanomedicine.

“…There are limited uses of other macrocycles in the formats that have been demonstrated for CD and CB[n] hosts. Indeed, work with other classes of macrocycles has relied primarily on recognition and inclusion of charged substrates by water‐soluble pillar[n]arenes or calix[n]arenes to induce reversible swelling/deswelling of a material or to facilitate assembly of a small molecule gelator through charge screening . These approaches, while effective in realizing hydrogel materials, do not typically rely on host–guest interactions to facilitate physical cross‐links, but rather employ alterations in solubility from hosts binding reversibly to cationic guests.…”

Hydrogel biomaterials are pervasive in biomedical use. Applications of these soft materials range from contact lenses to drug depots to scaffolds for transplanted cells. A subset of hydrogels is prepared from physical cross‐linking mediated by host–guest interactions. Host macrocycles, the most recognizable supramolecular motif, facilitate complex formation with an array of guests by inclusion in their portal. Commonly, an appended macrocycle forms a complex with appended guests on another polymer chain. The formation of poly(pseudo)rotaxanes is also demonstrated, wherein macrocycles are threaded by a polymer chain to give rise to physical cross‐linking by secondary non‐covalent interactions or polymer jamming. Host–guest supramolecular hydrogels lend themselves to a variety of applications resulting from their dynamic properties that arise from non‐covalent supramolecular interactions, as well as engineered responsiveness to external stimuli. These are thus an exciting new class of materials.
