Construction of Heterometallic Coordination Nanosheets Comprising Both Inert and Labile Metal Ions Together via Metalloligand Approach

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: April 3, 2025

Construction of coordination nanosheets (CONASHs) containing both inert and labile metal ions together is fundamentally significant but remains synthetically unachievable until now difficult to realize via conventional synthetic approach CONASHs due variable complexation conditions between heterometal organic ligands. Here, we demonstrate a strategy harness into structure by introducing the concept metalloligand. Metalloligands comprising ion (Os2+/Ru2+) free coordinating sites are designed synthesized can be further used as ligand bind (Fe2+) for building heterometallic (HMCONASHs). Following this, two HMCONASHs homoleptic complexes constructed that show broad absorption electrochemical window with reversible dual redox activity. Further, HMCONASH films exhibit multicolor electrochromism at different voltages, indicating their potential various applications. This may open create diverse structures functions hard achieve traditional approach.

Stimuli-Triggered Dynamic Transformations in Supramolecular Polymers

Chemistry of Materials, Journal Year: 2024, Volume and Issue: 36(13), P. 6347 - 6369

Published: June 24, 2024

Supramolecular polymers represent ordered nanostructures that are held together by highly directional noncovalent bonds and can undergo reversible self-assembly. Their nature imparts stimuli-responsive character to supramolecular polymers, making them appealing for the development of intelligent soft materials. As compared inherent responsiveness originating from connection units, incorporating additional units into monomeric structure allows customization stimuli-responsiveness polymers. Stimuli-triggered changes at molecular level amplify macroscopic effects due arrangement monomers. This review summarizes recent progress on stimuli-triggered transformations in categorizing five types: (i) depolymerization monomers, (ii) within different types (iii) post-stabilization (iv) activation dormant monomers situ polymerization, (v) transient polymerization with programmable lifetimes. Additionally, unconventional coupled equilibria complex systems is outlined. Emphasis design principles accumulated property response stimuli, aimed stimulating further research polymer field.

Injectable Conductive Hydroxylamine Nitrate Ionic Gel Materials Crosslinked by Xanthan Gum for Ultra-Fast Multiple Ignitions Response Via Electrical Stimulation

Published: Jan. 1, 2025

To achieve accurate and adjustable propulsion power, it is essential to utilize propellant materials undergoing repeated ignition combustion cycles. Injectable gel possess superior mechanical properties fluidity, allowing for the regulation of their process through precise control flow rate. Herein, an injectable conductive ion which uses hydroxylamine nitrate ([NH3OH]+[NO3]-, HAN) high-energy salt as matrix lithium perchlorate ( [Li]+[ClO4]-,AP) ammonium ([NH4]+[NO3]-, AN) adjust its conductivity was reported. The components this material exhibit high compatibility, confirmed by XPS FT-IR analysis, uniqueness conversion between liquid solid has established a good supply property. After centrifugation at 5000 r·min-1 15 min, eccentricity only 0.6%, demonstrating excellent stability. Compared with existing materials, delay time in single test reached 700ms under 225V 8ml·min-1. More importantly, can be reduced around 200ms after multiple tests, indicating ultra-fast response phenomenon that rarely occurs most research process, paving way realizing ultrafast application space propulsion.
