A thixotropic supramolecular metallogel with a 2D sheet morphology: iodine sequestration and column based dye separation

Abstract

Sequestration of hazardous radioactive iodine and dye separation to reduce industrial waste through reutilization is pivotal for environmental safety. In this regard, herein, synthesis of a new waterborne ultrasensitive supramolecular...

Establishment of different aliphatic amines-based rapid self-healing Mg(OH)2 metallogels: exploring the morphology, rheology and intriguing semiconducting Schottky diode characteristics

“…39 Self-healing metallogels are of significant concern for their very large number of practical uses, including electrical features and device-performances, 40 proton conductive devices, 41 absorption and separation. 30…”

“…5 Powered by these, research with the high-end technical prospect of soft-scaffolds, applicable to the oil industry, 6 sensing purposes, 7 electro-optics and photonics, [8][9][10][11][12] makeup materials, 13 catalysis, 14 drug carriage, 15 and biomedical uses, 16 began its journey decades ago. Metal-ion-directed soft-matter like metallogels attracts special attention due to its functional versatility in terms of magnetism, 17 electronic features including semiconducting behaviour, [18][19][20][21][22][23][24] redox properties, 25 sensing applications, 26 catalysis, 27 energy materials, 28 nonlinear optical performance, 29 separation, 30 etc. The self-restoring feature of a metallogel is beneficial for providing several functionally advanced durable flexible materials that can be quickly self-recovered as a priority.…”

A croconate-directed supramolecular self-healable Cd(ii)-metallogel with dispersed 2D-nanosheets of hexagonal boron nitride: a comparative outcome of the charge-transport phenomena and non-linear rectifying behaviour of semiconducting diodes

“…26,27 The fabrication of supramolecular metallogels, as a special class of soft multi-functional scaffolds, 28 is directed by the presence of diverse metal ions. [29][30][31][32][33][34][35][36][37][38][39] Recently, the utilization of diverse aliphatic/aromatic organic gelating constituents has been investigated as low molecular weight organic gelators for establishing stable metallogel systems. [40][41][42][43][44][45] Likewise, for decades, scientists have dedicated efforts towards the exploration of polyoxo-carbocyclic compounds, especially croconatebased materials, as croconate is significant owing to the presence of multiple neighbouring oxo-groups in it.…”

Pyridoxal-based low molecular weight progelator as a new chemosensor for the recognition of Ag+ and Hg2+ under different conditions

“…Low molecular weight gelators (LMWGs) or supramolecular gelators are an interesting and useful class of materials. The development of LMWGs for the construction of supramolecular gels and their subset, metallogels, have received immense interest in recent years due to their potential applications in a wide range of fields, including cell culture, 1,2 tissue engineering, 3,4 wound healing, 5 water purification, 6,7 drug delivery, 8,9 sensing and catalysis, 10,11 and optoelectronics. 12,13 These gels are viscoelastic semisolid materials that are formed owing to the self-assembly of small molecules into a large anisotropic three-dimensional (3D) network that entraps a large volume of solvent molecules.…”
