“…Recognizing this notable research gap, we decided to present a systematic analysis of glycolipid-based gelators to fill this void. To date, a large number of reviews are available in the literature featuring glycolipid gelators as one of the subsections explaining their several important properties. − ,,, In the provided articles, glycolipid-based gelators are regarded as merely one subset within the broader category of sugar-derived gelators, which may not fully encompass their significance. Therefore, the main purpose of this review is to bring together a detailed discussion of gelators based on glycolipids only.…”

Within the scope of this review, our exploration spans diverse facets of amphiphilic glycolipid-based low-molecular-weight gelators (LMWGs). This journey explores glycolipid synthesis, selfassembly, and gelation with tailorable properties. It begins by examining the design of glycolipids and their influence on gel formation. Following this, a brief exploration of several gel characterization techniques adds another layer to the understanding of these materials. The final section is dedicated to unraveling the various applications of these glycolipid-based supramolecular gels. A meticulous analysis of available glycolipid gelators and their correlations with desired properties for distinct applications is a pivotal aspect of their investigation. As of the present moment, there exists a notable absence of a review dedicated exclusively to glycolipid gelators. This study aims to bridge this critical gap by presenting an overview that provides novel insights into their unique properties and versatile applications. This holistic examination seeks to contribute to a deeper understanding of molecular design, structural characteristics, and functional applications of glycolipid gelators by offering insights that can propel advancements in these converging scientific disciplines. Overall, this review highlights the diverse classifications of glycolipid-derived gelators and particularly emphasizes their capacity to form gels.

“…As documented, MOFs have been widely used in sensing applications. [103][104][105] Taking a step ahead, MOF-based aerogels/hydrogels have progressed tremendously [31] as myriad gelators are explored based on bis(amino acid) oxalyl amides, [106] carbohydrate, [107] metalloporphyrins, [108] pyridine-pyrazole [109] and calix [4]arene, [110][111][112] tetraphenylethylene moieties, [113] glycolipid [114,115] and peptides [116,117] or amino acids like tyrosine [118] or tryptophan [119] for metallogel formation. Through the manipulation of metal-ligand interactions, these gels can exhibit specific responses to target molecules similar to those represented in Figure 1B, offering a versatile platform for sensing applications.…”

Chemosensing, an interdisciplinary scientific domain, plays a pivotal role ranging from environmental monitoring to healthcare diagnostics and (inter)national security. Metal‐organic gels (MOGs) are recognized for their stability, selectivity, and responsiveness, making them valuable for chemosensing applications. Researchers have explored the development of MOGs based on different metal ions and ligands, allowing for tailored properties and sensitivities, and have even demonstrated their applications as portable sensors such as paper‐based test strips for practical use. Herein, several studies related to MOGs development and their applications in the chemosensing field via UV‐visible or luminance along with electrochemical based are presented. These papers explored MOGs as versatile materials with their use in sensing bio or environmental analytes. This review provides a foundational understanding of key concepts, methodologies, and recent advancements in this field, fostering the scientific community.

“…Supramolecular gel represents an emerging class of materials that configure three‐dimensional (3D) fibrous networks of low‐molecular‐weight gelators (LMWGs) in a suitable solvent using noncovalent interactions such as hydrogen bonding, van der Waals interactions, π⋅⋅⋅π stacking, dipolar interactions, donor–acceptor interactions etc., providing a structure that is continuous and has macroscopic dimensions [1–25] . LMWGs are small organic compounds with a molecular mass of typically less than 2000 Da and which have the remarkable ability to entrap organic solvents (organogels) and pure water (hydrogels) even at low concentrations of the gelator [26–47,106] . A material is considered a gel if the entire liquid volume is immobilized at a definite concentration termed the critical gelation concentration (CGC), typically tested through the “tube inversion” method.…”

The use of lanthanide‐based metallogels presents a promising approach for the engineering of stimuli‐responsive gel materials. Stimuli‐responsive luminescent materials based on lanthanides have promising applications in bio‐applications and optical encoding. Synthetic supramolecular metallogels typically become kinetically trapped and usually do not exhibit time‐variable changes in their material properties. However, such supramolecular metallogels can switch between gel to sol when subjected to different external physical and chemical stimuli. This is because weak noncovalent interactions hold together the gel structure and are also influenced by the coordination dynamics of the metal‐ligand bond. This review summarizes recent research progress on stimuli‐responsive supramolecular lanthanide‐based luminescent metallogels. Chemical, physical, and multiple stimuli‐responsiveness of the metallogels are discussed elaborately based on the external stimulus sources. Finally, the latest challenges and opportunities for developing novel metallogels that respond to stimuli are discussed.
