“…ECL, also known as electrogenerated chemiluminescence, is an electro‐generation chemiluminescence technology that combines the excellent characteristics of electrochemistry and photoluminescence. The ECL method is characterized by the light emission generated from the electrochemically active substances through a high‐energy electron transfer process on an electrode surface producing highly reactive species in unstable excited states, that eventually produce luminescence upon relaxing to the ground state [11–14] . The ECL differs from chemiluminescence (CL) due to chemical reactions, photoluminescence (PL) due to the absorption of photons, and electroluminescence (EL) due to the direct conversion of electrical energy to light.…”

Electrogenerated chemiluminescence or electrochemiluminescence (ECL) is a chemiluminescence phenomenon generated by electrochemical reactions. Applying this phenomenon for metal ions detections is potentially effectual as it provides excellent selectivity and sensitivity as well as the ease of use and economical cost. Accordingly, the detection methods of many trace metals have been successfully developed by employing ECL systems, including Hg(II), Pb(II), Cu(II), Cd(II), Fe(III), Ag(I), Co(II), Cr(III), Cr(VI), Ni(II), and As(III). There are several key components required to comprise the ECL systems, including luminophores that emit light and are directly proportionate toward metal concentrations, co‐reactants that increase the number of excited luminophores, and electrodes where the electron transfer occurs. Some new ECL systems comprising luminophores, co‐reactants, and electrodes have been developed to achieve impressive measurement results with low detection limits. This paper aims to provide a comprehensive illustration concerning the development of ECL‐based metal sensors, to elucidate a development overview of key elements employed in ECL systems and their modifications, explaining the different types of interactions due to the presence of metal ions in ECL systems, as well as to discuss the future opportunities and challenges of the ECL systems.

Recently, chiral metal‐organic coordination materials have emerged as promising candidates for a wide range of applications in chiroptoelectronics, chiral catalysis, and information encryption, etc. Notably, the chiroptical effect of coordination chromophores makes them appealing for applications such as photodetectors, OLEDs, 3D displays, and bioimaging. The direct synthesis of chiral coordination materials using chiral organic ligands or complexes with metal‐centered chirality is very often tedious and costly. In the case of ionic coordination materials, the combination of chiral anions with cationic, achiral coordination compounds through noncovalent interactions may endow molecular materials with desirable chiroptical properties. The use of such a simple chiral strategy has been proven effective in inducing promising circular dichroism and/or circularly polarized luminescence signals. This concept article mainly delves into the latest advances in exploring the efficacy of such a chiral anion strategy for transforming achiral coordination materials into chromophores with superb photo‐ or electro‐chiroptical properties. In particular, ionic small‐molecular metal complexes, metal clusters, coordination supramolecular assemblies, and metal‐organic frameworks containing chiral anions are discussed. A perspective on the future opportunities on the preparation of chiroptical materials with the chiral anion strategy is also presented.

The dual‐functional device combining electrochromic properties and energy storage has gained numerous attentions in the field of energy‐saving smart electronics. However, achieving simultaneous optimization of coloration efficiency and energy storage capacity of materials poses a significant challenge. This study presents a novel approach by incorporating methyl orange into Prussian blue channels (PB‐MO films) to adjust the internal electronic structure of Prussian blue. This modification allows the active layer to simultaneously improve the electrochromic and energy storage performance. The introduction of methyl orange not only alters the ratio of Fe3+/Fe2+ within the framework through the coordination reaction of Fe3+ with methyl orange, but also improves the reaction kinetics after intercalating organic dye molecules, including charge transfer resistance, diffusion capability of ions and capacitive contribution. The PB‐MO films demonstrate remarkable properties: high optical contrast (81.4% at 670 nm), excellent coloration efficiency (265 cm2 C−1), and significant specific capacity (84 mAh m−2 at 0.05 A m−2), outperforming pure PB films. The PB‐MO films are ideally suited for applications in displays and intelligent energy storage fields, boasting both high coloration efficiency and substantial energy storage capacity, thus advancing promote the development of dual‐functional electrochromic devices.
