In response to increasing environmental and regulatory demands, developing synthetic strategies focused on sustainability and low-impact conditions has become a central focus in modern heterocyclic chemistry. Therefore, this review provides a comprehensive and critical analysis of low-impact methods reported over the past 8 years for constructing benzopyran-derived structures, including coumarins, flavones, chromones, chromenes, and chromanes. We systematically integrated both enabling technologies (e.g., microwave irradiation, visible-light photocatalysis, continuous-flow systems, and ultrasound activation) and chemical strategies involving biocatalysis, multicomponent reactions, recyclable heterogeneous catalysis, and alternative solvents, including deep eutectic solvents and ionic liquids. Advances in selectivity, efficiency, and catalyst reusability are highlighted, as are certain limitations. By contextualizing these methods within the various benzopyran scaffolds, this review provides an important foundation for the rational integration of sustainable tools in benzopyran synthesis and highlights perspectives for future research, thereby enhancing their industrial and pharmaceutical relevance.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70219"},"PeriodicalIF":8.9,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are fabricated by structurally integrating highly conductive and fluidic LMs with flexible and biocompatible hydrogels, thereby combining the advantages of both components. Three main preparation strategies include patterning LMs on hydrogel surfaces, injecting LMs into the interior of hydrogels, and directly mixing LMs with hydrogels. Smart LM hydrogel composites exhibit outstanding comprehensive performance of excellent electrical conductivity, self-healing capability, mechanical strength, adhesiveness, and biocompatibility, as well as multiresponsive behaviors to external stimuli, including strain, light, magnetic field, temperature, and humidity. Benefiting from these superior properties, smart LM hydrogel composites have found wide applications in cutting-edge fields such as wearable devices, disease therapy, actuators, electromagnetic interference shielding, and triboelectric nanogenerators. This review systematically correlates the structure-property-application relationships of smart LM hydrogel composites, with an emphasis on the synergistic enhancement mechanisms of LMs on the electrical conductivity, self-healing performance, mechanical properties, adhesiveness, biocompatibility, and intelligent responsiveness of hydrogels. Various application scenarios of smart LM hydrogel composites are also summarized. Smart LM hydrogel composites are expected to achieve more development in intelligent systems through optimizing structural design, tuning interfacial interactions, and expanding multifunctional integrated systems.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70245"},"PeriodicalIF":8.9,"publicationDate":"2026-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148900377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the roles of electrode materials, solid and quasi-solid electrolytes, current collectors, substrates, and electrode/electrolyte interfaces are discussed in relation to ion transport, charge transfer, voltage window, equivalent series resistance, and mechanical reliability. Second, recent progress in hierarchical electrodes, interface engineering, flexible architectures, self-charging systems, electrochromic devices, sensing-integrated platforms, and wearable configurations is critically assessed. Third, the review introduces an application-translation framework that connects material and device advances with engineering metrics such as power density, response time, cycling durability, leakage behavior, converter compatibility, module scalability, hybrid energy-storage operation, renewable-energy buffering, and grid-edge support. Persistent challenges, including limited ionic conductivity, interfacial resistance, constrained voltage windows, low practical mass loading, packaging instability, scale-up inconsistency, and nonstandardized testing, are also highlighted.

Traditional transition-metal-catalyzed methods often suffer from limitations such as metal contamination, high costs, and tedious workup procedures. In contrast, base-mediated/catalyzed systems have emerged as a prominent research hotspot owing to their metal-free nature, mild conditions, excellent functional group tolerance, and green economy. This review systematically summarizes the recent advances in base-mediated [5 + 1] cycloadditions over the past two decades. Based on the catalytic systems, the reactions are categorized into organic bases (tertiary amines, N-heterocyclic carbenes, organophosphines) and inorganic bases (potassium tert-butoxide, carbonates, and potassium methoxide). The cyclization modes involving various five-atom synthons with one-carbon/one-nitrogen synthons are discussed in detail. This review aims to provide a comprehensive theoretical reference for the future design of novel base-mediated cycloadditions and the construction of complex cyclic pharmaceutical skeletons.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70243"},"PeriodicalIF":8.9,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148863734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Revealing how these motions occur, the key interactions, and the rate-limiting steps determining their kinetics is essential for understanding and designing functional systems. However, due to scale-, space-, and time-resolution limits, this is typically not easy to access via experimental techniques. In this Personal Account, we discuss representative examples from our recent work using classical molecular dynamics and metadynamics simulations to investigate the key mechanisms, the thermodynamics, and kinetics of the internal dynamics of rotaxanes and catenanes. This allows access to the dynamics of mechanically interlocked systems at atomistic resolution, disentangling bound, unbound, and intermediate states and the dynamical interconversion between them, and providing information on kinetic barriers and characteristic timescales. Such atomistic-scale simulations provide results that are reliable and in very good agreement with the available experimental measurements. Overall, this account illustrates the value of molecular simulations as a predictive and complementary tool for understanding mechanically interlocked molecules in motion.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70238"},"PeriodicalIF":8.9,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148839371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particular attention is given to recent advancements in graphene-based composites. Finally, the paper discusses the major obstacles to the clinical translation of graphene-based composites, as well as the lack of standardized characterization and biosafety evaluation systems suitable for composite systems.

Among these, Bi2Te3-based thin films including alloys such as Bi2Te3-xSex and BixSb2-xTe3 are key candidates for microenergy systems due to their reduced dimensionality, which enhances phonon scattering and enables precise charge transport control. Thin-film architectures provide seamless integration with flexible substrates, engineered interfaces that suppress lattice thermal conductivity (κL), and millisecond-scale thermal response. This review critically examines fabrication techniques for Bi2Te3-based thin films, including physical vapor deposition (coevaporation, pulsed laser deposition, and magnetron sputtering), low-pressure chemical vapor deposition, solution-based methods (electrochemical deposition, spin-coating, and wet-chemical synthesis) and screen printing technique. Each deposition method is evaluated for stoichiometric control, microstructure, and interfacial quality, with process parameters linked to TE performance and optimized films demonstrated in flexible, wearable, and conformal devices. The analysis reveals a fundamental trade-off between TE efficiency, manufacturing scalability, and mechanical durability-a trilemma that no single deposition method can resolve.
