“…So, the detection of metal ions has received much attention due to their toxic effects on the environment. 1 Different methods such as high-performance liquid chromatography (HPLC), 2 inductively coupled plasma mass spectroscopy (ICP-MS), 3 inductively coupled plasma atomic emis-sion spectrometry (ICP-AES) 4 and atomic absorption spectroscopy (AAS) 3,5 are commonly used to identify metal ions. These methods have many limitations such as expensiveness, time-consuming process, and the need for advanced equipment.…”

“…The advantages of this easy-to-use optical instrument include no pollution, high processing speed, and controllability. 1 On the other hand, light can be limited to one area (focusing on a specific area) and if the response is reversible, it can be easily turned on and off. 6 Azobenzenes, 13 spiropyrans, 14 spirooxazines, 15 diarylethanes, 16 and fulgides 17 are the photochromic compounds used in different polymeric systems.…”

“…Rapid response to external stimuli and the relatively easy synthesis of the polymers containing spiropyran have led to the widespread application of this compound. 1,18 Colourless and non-planar spiropyran (SP) undergoes heterocyclic ring cleavage at the carbon-oxygen spiro bond under UV light and converts into the planar and highly conjugated form of merocyanine (MC) with strong absorption in the visible region. Heat or visible light (white or green) can return this isomer to its original form.…”

Adsorption‐based separations have the potential to enhance the sustainability of established industrial processes and facilitate the adoption of new practices. They also provide ways to meet emerging needs in the isolation of resources from non‐traditional supplies and the remediation of hazardous environmental contaminants. In this regard, there are significant opportunities to advance both fundamental polymer science and engineering applications through next‐generation adsorbent systems. Here, after briefly reviewing the history, potential application space, and underlying physics of polymer sorbents, design considerations that connect macromolecular design with systems‐level functionality, are discussed. First, polymer processing conditions are discussed in terms of the final nano‐ and microscale structures produced. Subsequently, the macromolecular chemistry of the materials is analyzed with respect to the ability of the separations systems to have analyte‐specific binding. Finally, a similar analysis is performed regarding the desorption mechanism used to release the target solutes. In this way, the manuscript attempts to connect macromolecular architecture with polymer physics and materials processing to provide guidance on how these important interrelationships impact the ultimate performance of sorbent systems.

Visible light is an important energy source for all living organisms on Earth. Given the importance of visible light, visible light sensors have attracted widespread interest from scientists. With the rapid development of wearable devices, the sensors used in them need to be flexible, stretchable, and lightweight. Herein, an intelligent electrolyte based on spiropyran (SP) that responds to visible light is developed. The reversible change rate in the electrical resistance of an SP/FeCl3·6H2O methyl cyanide (MeCN) aqueous solution under visible light irradiation is as high as 19.26%. Additionally, flexible and conductive fibrous visible light sensors with a core‐sheath structure are prepared using an SP/FeCl3·6H2O MeCN aqueous solution and silicon rubber hollow fibers as the core and outer layers, respectively. These fibrous visible light sensors are then woven into fabrics with multiple functions, such as sensing and locating visible light, reversible photochromism, and thermal management. The fibrous visible light sensors and fabrics prepared in this study have broad development prospects and application potential in the fields of fashion, smart textiles, flexible conductive fibers, flexible fibrous sensors, electronic skins, and wearable devices.
