Abstract
A rapid metallohydrogelation strategy has been developed of magnesium(II)-ion using trimethylamine as a low molecular weight gelator in water medium at room temperature. The mechanical property of the synthesized metallohydrogel material is established through the rheological analysis. The nano-rose like morphological patterns of Mg(II)-metallohydrogel are characterized through field emission scanning electron microscopic study. The energy dispersive X-ray elemental mapping analysis confirms the primary gel forming elements of Mg(II)-metallohydrogel. The possible metallohydrogel formation strategy has been analyzed through FT-IR spectroscopic study. In this work, magnesium(II) metallohydrogel (Mg@TMA) based metal-semiconductor-metal structures have been developed and charge transport behaviour is studied. Here, it is confirmed that the magnesium(II) metallohydrogel (Mg@TMA) based resistive random access memory (RRAM) device is showing bipolar resistive switching behaviour at room temperature. We have also explored the mechanism of resistive switching behaviour using the formation (rupture) of conductive filaments between the metal electrodes. This RRAM devices exhibit excellent switching endurance over 10,000 switching cycles with a large ON/OFF ratio (~ 100). The easy fabrication techniques, robust resistive switching behaviour and stability of the present system makes these structures preferred candidate for applications in non-volatile memory design, neuromorphic computing, flexible electronics and optoelectronics etc.

Abstract
The benzimidazole moiety, being a versatile heterocyclic unit, finds potential utility in
multiple applications ranging from material science to medicinal chemistry. Benzimidazole derivatives
are widely chosen as a multifunctional unit for the synthesis of bioactive organic compounds
because of their structural similarities to the natural nucleotides. They are also used as heteroaromatic
scaffolds in molecular probes for sensing and bio-imaging. Amphoteric nature of the benzimidazole
ring forms the basis of designing new fluorescent architectures for various metal ions, anions, nitroaromatics
as well as neutral organic molecules. Alongside, recent years have also witnessed the
emerging development of benzimidazole-based supramolecular gels, useful in sensing and water purification.
Supramolecular gels are a special class of self-assembled structures formed by weak noncovalent
interactions between the molecules and are easily tuned by external stimuli. Such stimuliresponsive
gels serve as smart materials because of their abilities to undergo gel-to-gel, or gel-to-sol
transition upon subtle change of the gel environment. Of various stimuli, ion coordination draws attention
for their visual detection and to adapt material properties. The ion-sensitive gels act as
fascinating biomaterials with potential applications in drug delivery, optoelectronics and catalysis.
Thus, designing of such ion-responsive gels is challenging. The rising popularity of benzimidazole
based-gels is related to its advanced properties such as π-bridging, hydrogen bonding, fluorescence
and ion coordinating abilities. This review focuses on recently developed various ion-responsive
benzimidazole motif-based supramolecular gelators by summarising the crucial role of the structural
parameters of benzimidazole gelators. Beside ion sensing, we also desire to summarize other possible
applications of gelators in material chemistry. Finally, the necessity and possibility of further exploration
of benzimidazole/ benzimidazolium derived gelators are briefly described.

Abstract
A novel coumarin-derived acylhydrazone Schiff base fluorescent organogel (G1) was designed and synthesized. Gelator G1 can form stable organogels in isopropanol, tert-amyl alcohol, n-butanol and phenylamine. The organogel could be converted to solution by heating and the solution could be restored to gel state by cooling. The self-assemble mechanism of G1 was investigated by XRD, FT-IR and SEM techniques. The results indicated the intermolecular hydrogen bonding, Van der Waals interaction and π-π stacking are the forces for the self-assembly of the gelator to form the organogel. The optical properties of the compound were studied by UV-visible spectroscopy and fluorescence spectra. Further study presented that gelator G1 could selectively and sensitively response to Fe3+ only among tested cations. Beside the above functions, the organic gel factor G1 could also response to irradiation, heating and shaking, thus endowing the organogel with multi stimulus responsive properties.

Abstract
Advances in the field of supramolecular chemistry have made it possible, in many situations, to reliably engineer soft materials to address a specific technological problem. Particularly exciting are "smart" gels that undergo reversible physical changes on exposure to remote, non-invasive environmental stimuli. This review explores the development of gels which are transformed by heat, light and ultrasound, as well as other mechanical inputs, applied voltages and magnetic fields. Focusing on small-molecule gelators, but with reference to organic polymers and metal-organic systems, we examine how the structures of gelator assemblies influence the physical and chemical mechanisms leading to thermo-, photo- and mechano-switchable behaviour. In addition, we evaluate how the unique and versatile properties of smart materials may be exploited in a wide range of applications, including catalysis, crystal growth, ion sensing, drug delivery, data storage and biomaterial replacement.
