With the development of single sensor to multi‐channel and multi‐mode sensor network, the sensor data also presents the characteristics of multi‐dimension, complex and massive. Traditional data analysis methods can no longer meet the data analysis requirements of hydrogel flexible sensor networks. The introduction of machine learning (ML) technology optimizes the process of data analysis. With the continuous development of multi‐layer neural network technology and the improvement of computer performance, deep learning (DL) algorithm is increasingly used to achieve higher efficiency and accuracy, provides a powerful tool for data analysis of hydrogel flexible sensor, and accelerates the intelligent process of hydrogel flexible sensor equipment. This paper introduces the classification of hydrogel flexible sensors and the working mechanism and common algorithms of ML, and summarizes the application of ML technology to assist hydrogel flexible sensors in data analysis in the fields of health care and information recognition. This review will provide inspiration and reference for integrating ML technology into the field of hydrogel flexible sensors.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a novel curing agent is constructed by the zirconium metal‐organic framework (UiO‐66) and [P4442]2[IDA] through an impregnation method. [P4442]2[IDA]@UiO‐66 is utilized as a functional nanofiller and curing agent to construct the [P4442]2[IDA]@UiO‐66/EP nanocomposites. The chemical structures of [P4442]2[IDA]@UiO‐66 were investigated by XRD, SEM, DSC, and TG characterizations. The various [P4442]2[IDA]@UiO‐66 with different loading amounts of [P4442]2[IDA] were used to investigate the curing behaviors of the EP‐51. The DSC results confirm that the curing temperature of the [P4442]2[IDA]@UiO‐66/EP is higher than that of [P4442]2[IDA]/EP. In addition, the kinetic parameters and the activation energy of the curing reaction were acquired according to the fitting of Kissinger equation and Ozawa equation. The drying time of [P4442]2[IDA]@UiO‐66/EP system at 40 °C was enhanced 17 times compare to that of [P4442]2[IDA]/EP system. This study opens new avenues for the rational design of EP nanocomposites by employing ionic liquids@MOFs composite materials as curing agent for wide engineering applications.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly intriguing within the realm of two‐component systems are those incorporating a photoswitchable molecule within a porous metal‐organic framework (MOF) host. In such configurations, the non‐covalently attached guest molecule undergoes distinct physicochemical changes influenced by factors like guest structure, guest density, and the shape of the MOF pores. In this study, fluorinated azobenzenes (Fx‐AZB) were introduced into the rigid UiO‐66 host, and the resulting optical properties were examined with a focus on the degree of fluorination. The photoisomers of all examined compounds exhibited remarkable stability under repetitive light exposure, showing no signs of fatigue. Moreover, both photoisomers remained stable at room temperature, defying the typical T‐type photochromism associated with azobenzenes. Most notably, all fluorinated azobenzene derivatives displayed nearly complete photoswitching upon exposure to visible light within the UiO‐66 MOF host. This positions these composite materials as leaders in the realm of azobenzene‐based switch@MOF systems.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140884502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single‐crystal structure analysis establishted that both compounds 1 and 2 exhibit two‐dimensional (2D) layered structures, while compound 3 features a three‐dimensional (3D) complicated framework. The geometries of metal ions vary from square pyramidal (in 1 and 3) to distorted octahedral (in 2). Topological strudy showed that compounds 1 and 2 have exposed common 4‐connected 44‐sql net, while compound 3 has made a novel 4,5‐connected net with point symbol of (43·62·7)(43·64·72·8). The catalytic performance of the three complexes for the solvent‐free ring‐opening polymerization of L‐lactide has been investigated. The results indicated that compound 3 with coordinatively unsaturated cobalt(II) sites showed very high activity and the molecular weight of the polymer obtained was also high. Moreover, the complex 3 catalyst could be recycled up to five times with the retention of both catalytic activity and crystal structure.","PeriodicalId":23934,"journal":{"name":"Zeitschrift für anorganische und allgemeine Chemie","volume":"68 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140664095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
