Itaconic and citraconic acid directed thixotropic and self-healable supramolecular metallogels of M(ii) (M = Co, Cu, Zn, and Cd) for the growth-inhibitory potency against human pathogenic microbes

Abstract

The present work explores the biological significances of two isomeric type organic constituents like itaconic acid (IA) and citraconic acid (CA) directed supramolecular metallogels of Cobalt(II), Copper(II), Zinc(II), and Cadmium(II)....

Solvent-Driven Variations of Third-Order Nonlinear Thermo-Optical Features of Glutaric Acid-Directed Self-Healing Supramolecular Ni(II) Metallogels

“…38 Now, the self-healing nature of any metallogel originates mainly due to polarity and conjugation-dependent capillary action within the three-dimensional gel network. 20 Alongside, higher-order nonlinearity is mostly observed in polar and conjugated systems. So we have targeted here to connect these two properties together and achieve higherorder nonlinear features in solvent-driven self-healing type flexible gel system.…”

“…The three-dimensional soft scaffold of supramolecular metallogel is constructed through various types of noncovalent interactions such as van der Waals interactions, hydrogen-bonding, electrostatic interactions, π–π stacking, etc., where the solvent molecules are immobilized. − Low-molecular-weight gelators (LMWGs), − having molecular mass less than 3000, are very crucial to forming supramolecular gel materials. The incorporation of different functional groups in gelator molecules such as hydroxyl, , carboxylic, − phosphate, along with nitrogen, oxygen, and sulfur containing compounds leads to diverse properties of metallogels. It offers potent functionality in different fields of biochemistry, catalysis, antipathogenic activity, medical diagnostics, drug delivery, − cell culturing, chemo sensors, − tissue engineering, − biomineralization, electrochemical devices, nonlinear optics, , lithography, pollutant removal, etc.…”

“…The self-healing process deals with the automatic repairing of physically damaged materials; the self-healing metallogels might be important, especially for the technologically advanced system . Now, the self-healing nature of any metallogel originates mainly due to polarity and conjugation-dependent capillary action within the three-dimensional gel network . Alongside, higher-order nonlinearity is mostly observed in polar and conjugated systems.…”

The synthesis and combined electrical–magnetic and toxic dye sequestration properties of a Cr(iii)-metallogel

“…22,23 Of particular interest are the adsorption related applications of the by default porous networks of metallogels along with their magnetic and electrical properties. 24–26 The electrical properties of MOFs depend heavily on the presence of infinite hydrogen bonded networks, which can result from encapsulated solvents or functional groups present inside their frameworks. 27,28 The metallogels that incorporate sufficiently large amounts of solvent molecules and that are sustained by infinite hydrogen bonded networks are therefore a natural choice for the study of their electrical properties.…”
