Abstract
A series of Ag(I) supramolecular organo-aqueous gels have been synthesized in the presence of an amine-rich triazole ligand as a gelator. Judicious choice of the triazole derivative and counter anion allows a desired spatial orientation of the pendant amine functionality to accentuate the gelation ability and autonomous self-healability via hydrogen bonding. In addition, the hydrogen bond donors, i.e. pendant -NH2 groups, offer a critical proximity of counter anions to the Lewis acidic Ag(I) and the reactants for promoting a three component coupling reaction of an aldehyde, a terminal alkyne and an amine, giving expedient access to propargyl amines, with remarkable functional group tolerance for both aromatic and aliphatic aldehydes, and aryl acetylenes. Experiments substantiate the pivotal role of counter anions and H-bonding interactions in the observed preference for propargylamines over the diacetylene by-product. Our catalyst is robust, bench-stable, and recyclable, and demonstrates a catalytic efficiency comparable to or better than those of reported systems. The catalyst was found equally effective for the gram-scale synthesis of propargylamines. Our approach lies at the intersection of metal-based, H-bond-mediated counter anion-tuned catalysis, evincing a potential for the development of purpose-built supramolecular gels for desired catalytic applications in the future.

Abstract
Metallogels formed from supramolecular interactions of low-molecular-weight gelators (LMWGs) combine the qualities of heterogeneous catalysts and offer the advantages of multifunctionality owing to the facile installation of desired task-specific moieties on the surface and along the channels of the gels. We discuss the applications of a triazole-based Ni(II) gel-derived xerogel (NiXero) having a high density of Ni(II)-nodes and appended primary amines as a recyclable heterogeneous catalyst for Knoevenagel condensation of aldehyde and malononitrile in water and the solvent-free cycloaddition of CO2 to form a series of cyclic carbonates with near-quantitative conversion of the respective epoxides, with low catalyst loading (0.59 mol %), high catalyst stability, and recyclability. The structural advantages of NiXero, due to the concurrent presence of bifunctional Lewis acid-base sites on the channels, open Ni(II) nodes, Ntriazole, pendant -NH2 and its chemical stability, are conducive to the cooperative heterogeneous catalytic activity under mild conditions. This work emphasizes the effective amalgamation of metals with purpose-built ligand systems for the construction of metallogels and their utility as heterogeneous catalysts for desired organic transformations.

Abstract
Carbohydrate-derived molecular gelators have found many practical applications as soft materials. To better understand the structure and molecular gelation relationship and further explore the applications of sugar-based gelators, we designed and synthesized eight trimeric branched sugar triazole derivatives and studied their self-assembling properties. These included glucose, glucosamine, galactose, and maltose derivatives. Interestingly, the gelation properties of these compounds exhibited correlations with the peripheral sugar structures. The maltose derivative did not form gels in the tested solvents, but all other compounds exhibited gelation properties in at least one of the solvents. Glucose derivatives showed superior performance, followed by glucosamine derivatives. They typically formed gels in toluene and alcohols; some formed gels in ethanol-water mixtures or DMSO water mixtures. The glycoclusters 9 and 10 demonstrated rate acceleration for the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. These were further studied for their metallogels formation properties, and the copper metallogels from compound 9 were successfully utilized to catalyze click reactions. These metallogels were able to form a gel column, which was effective in converting the reactants into the triazole products in multiple cycles. Moreover, the same gel column was used to transform a second click reaction using different reactants. The synthesis and characterization of these compounds and their applications for catalytic reactions were discussed.

Abstract
Metallogels have attracted a great deal of interest because of their intriguing properties and applications in chemsensors, batteries, catalysis, and other fields. In this work, a novel ligand bearing terpyridine and hydroxyamine units was designed and synthesized. The ligand selectively gelated with copper ions in water by heating and cooling or sonication. Different physicochemical studies [Fourier transform infrared, ultraviolet-visible (UV-vis), electron paramagnetic resonance (EPR), scanning electron microscopy, X-ray diffraction, and rheology] were conducted to characterize the gels. We show that coordination interaction, π-π interaction, and noncovalent interaction had obvious effects on the properties of the gel. Additionally, a stable radical hydrogel could be obtained by ultrasound treatment, which was accompanied by color variation from green to blue. This was further confirmed by UV-vis and EPR experiments. Furthermore, the copper metallogels were developed as catalysts for the preparation of 1,2,3-triazole derivatives in water at 25 °C. Although various types of catalysts have been investigated, the use of metallogels as catalysts for the click reaction in water has been scarce. This strategy shows the process is simple, affords a high yield, and is "green" and economical.

Abstract
Metal-organic gel (MOG), as a novel type of metallic organic hybrid material, exhibits diverse properties. However, its application in fluorescence detection for specific metal ions has rarely been exploited. In this work, we have designed and synthesized a MOG based on Al-carboxylate coordination assemblies (denoted as MOG-Al). The resultant MOG-Al shows good specific fluorescence signal response to trace Cu2+. Under optimal conditions, the fluorescence quenching degrees (F0 - F) of the MOG-Al have a linear correlation with Cu2+ concentration ranging from 0.05 to 100 μM, and the limit of detection (LOD) is 45.00 nM. The proposed sensing platform was also applied for the detection of Cu2+ in real samples. Satisfactory recoveries (92-116%) for Cu2+ in rice, soybean milk powder and pork liver were obtained. These results indicate that MOG-Al is a promising material for the specific and sensitive sensing of Cu2+.

Abstract
Glycoclusters with three, four, and six arms of glycosyl triazoles were designed, synthesized, and characterized. The self-assembling properties of these molecules and their catalytic activity as ligands in copper-catalyzed azide and alkyne cycloaddition (CuAAC) reactions were studied. The compounds with a lower number of branches exhibit excellent gelation properties and can function as supramolecular gelators. The resulting gels were characterized using optical microcopy and atomic force microscopy. The glycoconjugates containing six branches showed significant catalytic activity for copper sulfate mediated cycloaddition reactions. In aqueous solutions, 1 mol % of glycoclusters to substrates was efficient at accelerating these reactions. Several trimeric compounds were found to be capable of forming co-gels with the catalytically active hexameric compounds. Using the organogels formed by the glycoconjugates as supramolecular catalysts, efficient catalysis was demonstrated for several CuAAC reactions. The metallogels with CuSO4 were also prepared as gel columns, which can be reused for the cycloaddition reactions several times. These include the preparation of a few glycosyl triazoles and aryl triazoles and isoxazoles. We expect that these sugar-based soft biomaterials will have applications beyond supramolecular catalysis for copper-catalyzed cycloaddition reactions. They may also be useful as ligands or gel matrixes for other metal-ion catalyzed organic reactions.

Abstract
1,2,3-triazoles are popular heterocycles employed in material sciences and medicinal
chemistry as they show antiviral, antibacterial, anti-HIV, antitubercular, and antifungal
activities. Triazoles are appealing due to their stability and interesting click chemistry
properties. The Cu(I) catalyzed reaction between azides and alkynes affords the 1,4-
disubstituted derivative exclusively becoming a useful synthetic tool. However, one of the
main drawbacks of the catalyzed reaction is the need to use Cu(I), which is unstable at
standard conditions and rapidly oxidizes to the non-active Cu(II). The most common approach
when synthesizing 1,4-disubstituted-1,2,3-triazoles is to reduce Cu in situ employing
inorganic Cu salts and a reducing agent. The resulting Cu(I) needs to be further stabilized
with organic ligands for the reaction to take place. The aim of homogeneous catalysis
is to produce a ligand with a dual function both in reducing and stabilizing Cu(I) without interfering in the
overall reaction. Instead, heterogeneous catalysis offers more options when supporting Cu on nanoparticles,
complexes, and composites yielding the desired 1,2,3-triazoles in most cases without the need of a reducing
agent under green solvents such as ethanol and water. The catalytic activity of Ag, Ru, and Ce is also discussed.
This review exemplifies how the use of homogeneous and heterogeneous catalysts offers new and
green methodologies for the synthesis of 1,2,3-triazole derivatives. The materials supporting Cu show catalytic
properties like high surface area, acid-base sites or phase transfer. Although there is no ideal catalyst, Cu remains
the most effective metal since it is economical, abundant and readily available.

Abstract
We report the in situ formation of Ni-based supramolecular organogel and organic-aqueous gels using amine appended triazole ligand, having varying morphology and rheological properties. These gels are self-healable and moldable or injectable respectively depending on the absence or presence of water in the gelation medium. Our studies reveal that the formation and rupture of hydrogen bonds assisted by the solvent movement is responsible for the self-healing nature of the gels. The porous structure of the gel has been observed from the migration of dye molecules on the self-healed gel. In addition, the gels show dual function of reversible adsorption of toxic gases and sequestration of heavy metal ions, especially palladium via gel-to-gel transformation. It is imperative to stress that such transformation is extremely rare for small molecule based metallogels. The dynamic nature of Ni-Ntriazole interactions has been utilized in achieving the reversible gas/vapor responsive behavior of the metallogels, which could be suitable in developing colorimetric probes for the detection of toxic gases and heavy metal ions. Such multifunctional gels are exceptional in contemporary literature and are expected to find utility in fabricating smart multistimuli-responsive gel-based materials in the future.

Abstract
A supramolecular gel is a fascinating combination of flexibility and orderliness. While the supramolecular nature of crosslinking contributes towards the adaptivity and the reversibility of the system, orderliness at the molecular level amplifies the functional output and induces extraordinary selectivity into the system. Therefore, use of supramolecular gels as the soft template is an emerging area of research, which includes but not limited to catalysis of a chemical or a photochemical process, transcription of gel property to a substrate, or even controlling the nucleation of drug molecules. This review aims to highlight the template effect of supramolecular gels in the above-mentioned areas relevant to novel fundamental chemistry, technology, and healthcare.

Tandem Catalysis of an Aldol-'Click' Reaction System within a Molecular Hydrogel. Molecules 2016; 21:molecules21060744.

Abstract
A heterogeneous supramolecular catalytic system for multicomponent aldol-‘click’ reactions is reported. The copper(I) metallohydrogel functionalized with a phenyltriazole fragment was able to catalyze the multicomponent reaction between phenylacetylene, p-nitrobenzaldehyde, and an azide containing a ketone moiety, obtaining the corresponding aldol products in good yields. A possible mechanistic pathway responsible for this unexpected catalytic behavior has been proposed.
