Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401201-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A strong electrostatic MV²⁺‐GQD nanocomposite</bold> provides an electrolyte‐free flexible electrochromic device wih high durability. The positively charged MV²⁺ and negatively charged GQD are strongly stabilized by non‐covalent intermolecular forces (e.g., electrostatic interactions, π–π stacking interactions, and cation‐π electron interactions), eliminating the need for an electrolyte. An electrolyte‐free flexible electrochromic device fabricated from the GQD‐supported MV²⁺ exhibits stable performance under mechanical and thermal stresses. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh112xhjg6" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
