“…Nanoscale metal−organic frameworks (NF-MOFs) are a novel class of 2D nanomaterials distinguished by their unique porous structures and tunable chemical functionalities. 66 These attributes endow NF-MOFs with distinct advantages, including a high surface area for efficient charge trapping and excellent mechanical properties for robust device integration. When combined with SF, the resulting composite films exhibit remarkable enhancements in the output performance of TENGs.…”

Triboelectric nanogenerators (TENGs) developed from eco-friendly natural materials rather than traditional electronic materials are more favorable for biocompatible applications and for use in sustainable life-cycle analysis. Silk fibroin (SF) has emerged as an abundant natural biomaterial that shows great potential in the preparation of TENGs. Silk-based triboelectric nanogenerators (SF-TENGs) have green energy harvesting properties, are environmentally friendly, are biocompatible, are not fully present in conventional TENGs, and are important for the next generation of selfpowered electronic devices. In this review, the latest progress in SF-TENGs, including their applied materials, structural properties, manufacturing processes, and application scenarios, is discussed. These SF-TENGs show great potential for use in emerging energy and electronic applications as well as smart living and medical assistance. In addition, the potential value of SF-TENGs has been further explored, and the possibility and main challenges of expanding and applying SF-TENGs to the field of microneedles (MNs) are discussed.

“…As a type of inorganic–organic hybrid material, coordination polymers (CPs) are assembled from the coordination between organic linkers and metal cations/clusters with repeating coordination entities extending in 1, 2, or 3 dimensions and have emerged as one of the most fascinating candidates of luminescent materials in the field of fluorescence sensing, − light-emitting diodes (LEDs), , bioimaging, nonlinear optics (NLOs), , upconversion materials, , and so on, due to tunable luminescence properties. , Among various CPs, the entities with potential voids that are usually well-known as porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) have been of the most concern and gained tremendous success in various fields due to structural diversity, high porosity, large surface area, and easy modification. − Additionally, external stimuli can induce significant changes in the fluorescence properties of CPs through varieties of mechanisms, including structure transformation/collapse, size exclusion, energy transfer, photoinduced electron transfer (PET), guest exchange, and so on, − which offer the feasibility of employing CPs to serve as fluorescent sensing materials. Thus, tremendous efforts have been devoted to the exploration of CPs as fluorescent sensors and quantities of CPs have displayed outstanding fluorescence sensing performance for varieties of chemicals, including hazardous gas, volatile organic compounds (VOCs), explosives, pesticides, antibiotics, amino acids, or parameters such as pH and temperature. , Although various metal cations could be employed to prepare CPs, transition metal cations with d 10 electron configuration, especially Zn(II) and Cd(II), are of special concern in the construction of fluorescent CPs due to their potential superior fluorescence properties originating from the possible ligand-to-metal charge transfer (LMCT) process. ,− …”

Owing to the large-scale consumption of pesticides and their potential threats to the environment and human health, the development of sensing materials for pesticides has attracted considerable attention in recent years. In this work, a novel Cd(II)-based coordination polymer (CP) with the formula [Cd(H 2 O) 2 (L)]•DMF (Cd-1, DMF = N,N-dimethylformamide, H 2 L = 4,4′-[(2,5-dimethoxy-1,4-phenylene)di-2,1-ethenediyl]bis-benzoic acid) was synthesized under solvothermal conditions. Structural analysis revealed that coordination between central Cd 2+ cations and the ligand L 2− formed two-dimensional (2D) networks, which were further assembled by noncovalent hydrogen bonds into a three-dimensional (3D) supramolecular framework. Through ultrasonic treatment in isopropyl alcohol, Cd-1 was exfoliated to afford an ultrathin CP-based 2D nanosheet (Cd-1-NS) with a thickness of less than 1.8 nm. Compared to the bulk materials, the prepared Cd-1-NS exhibited enhanced fluorescence emission properties and superior sensing performance toward glyphosate (Glyph) in water with high selectivity, sensitivity, anti-interference, fast response, and good recyclability via the turn-off effect. The limit of detection (LOD) of Cd-1-NS for Glyph was as low as 41 nM (7 ppb) in the low-concentration range of 0−2.4 μM. In addition, the Cd-1-NS also showed excellent practicability and reliability for the detection of Glyph in real samples, including lake water, tap water, cabbage, and watermelon skin, and could realize the rapid visualized sensing of Glyph residues on the surfaces of vegetables and fruits.

As the fourth full‐nitrogen structure, the pentazolate anion (cyclo‐N5−) was highly coveted for decades. In 2017, the first air‐stable non‐metal pentazolate salt, (N5)6(H3O)3(NH4)4Cl, was obtained, representing a milestone in this field. As the latest member of the azole family, cyclo‐N5− is comprised of five nitrogen atoms. Although significant attention has been paid to the potential of cyclo‐N5− as an energetic material, its poor thermostability hinders any practical application. However, the unique ring structure and multiple coordination capability of cyclo‐N5− provide a platform for the fabrication of various structures, among which pentasil‐zeolite topologies are the most intriguing. In addition, the introduction of structure‐directing auxiliaries enables the self‐assembly of diverse topological architectures, potentially imparting cyclo‐N5− with the potential to impact wide‐ranging areas of coordination chemistry and topology. In this minireview, different pentasil‐zeolite topologies based on metal‐pentazolate frameworks are evaluated. To date, three zeolitic and zeolite‐like topologies have been reported, namely the melanophlogite (MEP), chibaite (MTN), and unj topologies. The MEP topology consists of two nanocages, Na20N60 and Na24N60, whereas the MTN topology contains Na20N60 and Na28N80 nanocages. Furthermore, the unj topology features multiple homochiral channels consisting of two helical chains. Various possible strategies for obtaining additional pentasil‐zeolite topologies are also discussed.
