The fabrication of self-driven systems with flexibility and tunable output for organic photoinduction is highly desirable but challenging. In this study, a 3D cadmium metal-organic framework (Cd-MOF) synthesized used as filler ethyl cellulose (EC) to create mechanically durable flexible Cd-MOF@EC composite films. Due its well-established platform periodically precise structure nature, the outputs Cd-MOF-based TENG are much higher than those ligand-based TENGs. Furthermore, films different doping ratios Cd-MOF employed assemble Cd-MOF@EC-based triboelectric nanogenerators (TENGs). results reveal that ratio 10 wt.% in provides highest output. Subsequently, (FCEC-TENG), working contact-separation model, constructed harvest mechanical energy from human body, demonstrating excellent performance stability. harvested FCEC-TENG can directly illuminate 14 commercial white light-emitting diodes (LEDs), providing visible light bromination reaction, generating bromide good yield tolerance. This study presents an effective method constructing MOF-based self-powered photoinduced transformation systems.

Abstract Defect‐engineering‐involved metal‐organic frameworks (MOFs) have been highly valued in many fields due to the enhanced porosity and abundant active sites, but how systematic modulation on deficiency influencing fluorescent sensing performance is still its infancy. Here, defect‐engineering of MOF‐525 used modulate exposure zirconium (Zr) clusters sieving capability inner channels, enabling precise phosphoryl fluoride nerve agents with specific chemical activity molecular dimensions. Controllable defects transformed localized emission porphyrin into ligand‐metal charge transferring (LMCT) gradual loss ligand molecules, which interrupted upon coordination agents, triggering a red turn‐on fluorescence. Thus, defective 60% effectively discriminates (e.g., sarin, soman) from similar substances tabun, venomous agent X) synergistic effect dimension. It exhibits sensitive (0.96 n m /3.8 ppb), rapid (<1 s) response toward target robust environmental interference acidic, humid common substances. This work enhances understanding MOFs correpsonding luminescent behavior, paving new avenue for strategy trace real vapor.

Long-range charge transport (LRCT) in molecular wires is crucial for the advancement of electronics but remains insufficiently understood due to complex mechanisms and their dependencies on structure. While short-range typically dominated by off-resonant tunneling, which decays exponentially with length, recent studies have highlighted certain structures that facilitate LRCT minimal attenuation over several nanometers. This Perspective reviews latest progress understanding LRCT, focusing chemical designs enable this phenomenon. Key strategies include π-conjugation, redox-active centers, stabilization radical intermediates, support through such as coherent resonant tunneling or incoherent hopping. We discuss how effects structure, temperature influence transport, highlight emerging techniques like Seebeck effect distinguishing between mechanisms. By clarifying principles behind outlining future challenges, work aims guide design systems capable sustaining efficient long-distance thereby paving way practical applications beyond.
