“…For instance, the electrodeposition of silver ions dissolved in a transparent electrolyte on a rough surface results in the formation of a silver black layer that absorbs incident light. Alternatively, ECDs can utilize organic, , inorganic molecules or hybrid materials that change color upon reversible electrooxidation/electroreduction that takes place in the same phase.…”

The article describes novel electrochromic materials (ECMs) that are based on a monolayer consisting of two or three isostructural metal complexes of 4′-(pyridin-4-yl)-2,2’:6′,2’’-terpyridine simultaneously deposited on surface-enhanced support. The support was made by screen printing of indium tin oxide (ITO) nanoparticles on ITO-glass and has a surface area sufficient for a monolayer to give color visible to the naked eye. The ability to separately electrochemically address the oxidation state of the metal centers on the surface (i.e., Co2+/Co3+, Os2+/Os3+, and Fe2+/Fe3+) provides an opportunity to achieve several distinct color-to-color transitions, thus opening the door for constructing monolayer-based multicolor ECMs.

“…[35,36] Furthermore, triazine and its derivative groups are also excellent electron-withdrawing acceptors and can be linked with donor units (such as triphenylamine, carbazole or acridine) to form organic light-emitting compounds. [37] In this work, a triazine-based fluorescent dye library containing 1,536 compounds was synthesized in three steps based on the temperature-mediated selective reaction of 1,3,5-trichloro-2,4,6-triazine (TCT). As shown in Figure 1b,c, the fluorescent framework with two chlorine atoms (4-(4,6dichloro-1,3,5-triazin-2-yl)-N,N-diphenylbenzenamine, TT) was constituted first via Suzuki cross-coupling reaction of TCT and 4-(diphenylamino)phenylboronic acid at 50 °C.…”

The Materials Genome Initiative (MGI) is accelerating the pace of advanced materials development by integrating high‐throughput experimentation, database construction, and intelligence computation. Live‐cell imaging agents, such as fluorescent dyes, are exemplary candidates for MGI applications for two reasons: i) they are essential in visualizing cellular structures and functional processes, and ii) the unclear relationship between the chemical structure of fluorescent dyes and their live‐cell imaging properties severely restricts the current trial‐and‐error dye development. Herein, the MGI is followed to present an intelligent combinatorial methodology for predicting the staining cell ability of dyes utilizing machine learning (ML) driven by a structurally diverse combinatorial library. This study demonstrates how to high‐throughput synthesize 1,536 dyes and evaluate their imaging properties to establish a feature dataset for ML. A set of high‐precision ML‐predictors is then successfully modeled for assisting live‐cell staining and endoplasmic reticulum judgment. This approach is believed to bridge the gap between dye structure and corresponding staining behavior, and can accelerate the discovery of novel organelle‐specific stains.

“…Significant thermal, chemical, and tunable physicochemical stability along with pore size, large surface area, and low skeleton density remain very important among them. − In this particular work, we have utilized the advantage of incorporation of viologens, an N , N ′-disubstituted-4,4′-bipyridinium moiety, which is an electron-accepting dicationic organic structure with an excellent reversible redox property and fast electron transfer ability, to generate an ionic porous organic polymer (iPOP-Bpy). The polymer contains an electron-withdrawing triazine moiety in the core, which is a suitable electron acceptor with favorable electron-conducting properties. − The cationic nature of the polymer, nitrogen-rich structure, physicochemical stability, and presence of an aromatic skeleton make it a suitable candidate to explore its capacity for iodine adsorption. The importance of iodine adsorption study lies in the fact that in the nuclear power energy sector, among various nuclear toxic wastes, the generation of volatile radionucleotides of iodine 129 I and 131 I is considered one of the dangerous atomic wastes due to its volatility which is hard to control, and it can readily diffuse in the environment and contaminates it.…”

Here, we report the design and synthesis of a redoxactive multifunctional ionic porous organic polymer iPOP-Bpy with exchangeable Br − ions, incorporating viologen as a redox-active building block. The material shows not only excellent iodine uptake capacity in the vapor phase (540 wt %) but also in the organic (1009.77 mg g −1 ) and aqueous phases (3921.47 mg g −1 ) with very fast adsorption kinetics in all cases. The material also shows its utility in being used as a solid-state NH 3 vapor sensor as it shows very fast color switching in the presence of NH 3 vapor. Furthermore, the material found application as a p-type complementary electrochromic electrode and was fabricated into a bilayer device. Excellent coloration efficiency, high switching speed, and good color contrast were obtained as investigated using bias-dependent optical and spectroelectrochemical studies, paving the way for fabricating power-efficient solid-state electrochromic devices.
