Abstract

Metallopolymers are hybrid materials made from both organic and inorganic components, with adjustable properties that make them great for advanced uses. This study focuses on the synthesis and characterization of Ru(II)-metallopolymers using positionally isomeric ditopic ligands with multiple binding sites, enabling stable metal-ligand complexes and the growth of linear polymer chains. Analytical techniques such as ATR-IR, NMR, UV–Vis, and electrochemical methods were employed to assess their structural, electronic, and redox properties. A detailed investigation of specific capacitance in various electrolytes revealed capacitance values of 131 Fg⁻¹ in 1 M H₂SO₄ for Ru(II)-L₁ Poly and 130 Fg⁻¹ in LiClO₄ for Ru(II)-L₂ Poly, with robust cyclic stability retaining 98 % of initial capacitance after 8000 cycles. These metallopolymers offer superior compatibility and flexibility with organic conjugated polymers, making them ideal for making hybrid energy storage devices. Their excellent retention and stability underscore their potential as redox additives in supercapacitors. This work not only addresses gaps in energy storage research but also highlights the adaptability of Ru(II)-metallopolymers in developing high-performance, electrochemical materials for advanced energy technologies.

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
