Redox‐Induced Molecular Metamorphism Promoting a Sol/Gel Phase Transition in a Viologen‐Based Coordination Polymer

“…At this stage, one should however be cautious about correlating the sol/gel phase change to a specific reorganization process. Gel formation implies the existence of three‐dimensional networks but there are precedents in literature showing that metal‐organic gels can as well involve discrete molecules or coordination polymers . In the absence of further information, it is thus still not clear whether reduction leads to a dissociation of the self‐assembled coordination polymer to yield discrete/macrocyclic compounds or to a drastic change in the organization of the tectons within the polymeric assemblies (Figure ).…”

[64][65][66][67][68][69][70] In the absence of further information, it is thus still not clear whether reduction leads to ad issociation of the self-assembled coordination polymer to yield discrete/macrocyclic compounds or to ad rastic change in the organization of the tectons within the polymeric assemblies (Figure 1). Further investigations are currently underway to clarify this key issue.…”

A Supramolecular Gel of Oxalic Acid‐Monoethanolamine for Potential Schottky Barrier Diode Application

“…Gels are soft‐viscoelastic 3D scaffolds materialized through the self‐assembly of molecules by immobilizing high throughput of trapped solvent (both organic and aqueous) via different supramolecular non‐covalent intermolecular interactions like solvo‐phobic, ionic, hydrogen bonding, halogen bonding, aryl moiety based stacking features, van der Waals, etc Low‐molecular‐weight gelators (LMWGs), a special type small molecules having molecular mass of typically less than 3000, are brilliantly potent to immobilize solvents to get chemical constituents‐based semi‐solid 3D gel materials . Literary, LMWGs based gelation process basically offers supramolecular gel materials full of inter‐connected non‐covalent facets .…”

Gel Formed by Self‐Assembly of a Urea‐Modified Monopyrrolotetrathiafulvalene Derivative Displays Multi‐Stimuli Responsiveness and Absorption of Rhodamine B

“…[8] In 1994, Jørgensen and co-workers first introduced the self-assembled molecular wires based on TTF gel. [11] Also, doping the xerogels of TTF based organogels with oxidative species notably induced charge transfer (CT) complexes and resulted in high electrical conductivity. [10] And Oshio et al constructed a TTF substituted multi-redox active metallogelator based on a mixed-metal octanuclear complex.…”

[11] Also, doping the xerogels of TTF based organogels with oxidative species notably induced charge transfer (CT) complexes and resulted in high electrical conductivity. [12] In recent years, considerable efforts have been discussed in detail the supramolecular recognition and chargetransfer properties of nonaromatic TTF-pyrrole systems, [13] as well as many organogels with multiple-stimulus responsive properties based on monopyrrolotetrathiafulvalene (MPTTF) containing different functional units have been explored.…”
