Heteroatom-Doped Nickel Oxide Hybrids Derived from Metal-Organic Frameworks Based on Novel Schiff Base Ligands toward High-Performance Electrochromism

Zhiqiang Zeng et al.

Summary: The principles of coordination chemistry are utilized in designing and developing nanostructured materials based on metal-organic frameworks (MOFs). The application of Schiff base system to MOF derivatives introduces heteroatoms into carbon-based metal oxides for electrochromic applications, with the presented Ni-MOF thin films prepared through a reductive electrosynthesis approach showing promising electrochromic properties.

Fast-Switching Vis-IR Electrochromic Covalent Organic Frameworks

Derya Bessinger et al.

Summary: Electrochromic thin films based on covalent organic frameworks (COFs) exhibit high coloration efficiency and fast switching speeds, with reversible absorption changes of close to 3 OD triggered at low operating voltages and low charge per unit area. The champion material reaches a coloration efficiency of 858 cm(2) C-1 at 880 nm and maintains >95% of its response over 100 oxidation/reduction cycles, with extremely fast response times below 0.4 seconds for oxidation and around 0.2 seconds for reduction.
