“…Huang et al also found that the color of the emission of a lanthanide–cholate hydrogel depends on different lanthanide ions or codoping ions. 454 Utilizing the iminodiacetic acid ( 161 ) as a ligand to coordinate with lanthanides, Alves et al 455 prepared a series of hydrogels with the lowest CGC value at 0.04 wt %. Banerjee et al 456 designed a series of tyrosine-based amphiphiles ( 162 ) which bind with Ni 2+ ion selectively and result in hydrogels at CGC values of 0.78, 0.75, and 0.63 wt % when the chain length is 10, 12, and 14, respectively.…”

In this review we intend to provide a relatively comprehensive summary of the work of supramolecular hydrogelators after 2004 and to put emphasis particularly on the applications of supramolecular hydrogels/hydrogelators as molecular biomaterials. After a brief introduction of methods for generating supramolecular hydrogels, we discuss supramolecular hydrogelators on the basis of their categories, such as small organic molecules, coordination complexes, peptides, nucleobases, and saccharides. Following molecular design, we focus on various potential applications of supramolecular hydrogels as molecular biomaterials, classified by their applications in cell cultures, tissue engineering, cell behavior, imaging, and unique applications of hydrogelators. Particularly, we discuss the applications of supramolecular hydrogelators after they form supramolecular assemblies but prior to reaching the critical gelation concentration because this subject is less explored but may hold equally great promise for helping address fundamental questions about the mechanisms or the consequences of the self-assembly of molecules, including low molecular weight ones. Finally, we provide a perspective on supramolecular hydrogelators. We hope that this review will serve as an updated introduction and reference for researchers who are interested in exploring supramolecular hydrogelators as molecular biomaterials for addressing the societal needs at various frontiers.

“…To date, there have been several reports in the literature on lanthanide-ion-based metallogels. Holten-Andersen and co-workers reported white-light-emitting multistimuli-responsive lanthanide-ion-based metallogels. , Alves Jr. and co-workers reported β-amino acid- and lanthanide-ion-based supramolecular luminescent hydrogels . Maitra et al demonstrated facile metallogel formation of several lanthanide(III) cholates .…”

An intriguing functional supramolecular Tb(III)-metallogel (Tb-OX) is derived through the sonication of terbium(III) chloride hexahydrate and oxalic acid dihydrate in N,N-dimethylformamide (DMF) solvent under ambient conditions. A rheological investigation proves the mechanical stability of the supramolecular Tb-OX metallogel. Field emission scanning electron microscopy (FESEM) microstructural analysis unveils the rocklike morphological pattern of the Tb-OX metallogel having a supramolecular network. Metallogel synthesis, crystallinity, and thermal behavior of Tb-OX are evaluated with the help of IR spectroscopic investigations, powder X-ray diffraction (PXRD), and thermogravimetric analysis (TGA). Exhaustive investigations and analyses of the optical and electrical parameters of Tb-OX establish the semiconducting properties of the Tb-OX metallogel. Based on its conducting properties, the Tb(III)metallogel is successfully applied to a metal−semiconductor junction-based photosensitive Schottky barrier diode device with excellent charge transport properties.

“…7,14,15 Recently, we demonstrated a novel class of photochromic hydrogels obtained from lanthanide oxides (Ln 2 O 3 ) and iminodiacetic acid (H 2 IDA). 16 These eco-friendly lanthanide-organic gels (LOGs) were easily obtained hydrothermally under soft conditions, using only a few reagents at low temperatures without the need for any organic solvent. Even so, they presented remarkable optical properties in the visible region provided by the Eu 3+ and Tb 3+ ions.…”

A multifunctional smart supramolecular platform based on a lanthanide-organic hydrogel is presented. This platform, which provides unique biocompatibility and tunable optical properties, is synthesized by a simple, fast, and reproducible eco-friendly microwave-assisted route. Photoluminescent properties enable the production of coated light-emitting diodes (LED), unique luminescent barcodes dependent on the excitation wavelength and thin-films for use in tamper seals. Moreover, piroxicam entrapped in hydrogel acts as a transdermal drug release device efficient in inhibiting edemas as compared to a commercial reference.
