Understanding the gold core‐ligand interaction in gold nanoclusters (GNCs) is essential for the on‐demand tailoring of their photoluminescence properties and long‐term stability. Here, inspired by the suckers arranged directionally on the tentacles of octopus, a series of GNCs with regulating ligand structures are grown and stabilized on the cellulose nanocrystals (CNCs). The carboxylated CNCs providing...
Gold Nanoclusters
Inspired by the unique structure of octopus suckers arranged directionally on its tentacles, a series of gold nanoclusters (GNCs) grown in situ along cellulose nanocrystals are synthesized. The fluorescence properties and oxidative properties of GNCs are investigated, and a generalized strategy for constructing DCGRFP is provided. More In article number 2307770, Hongxiang Zhu, Hui...
Chloramphenicol (CAP) has long been used extensively in agriculture and is severely toxic to the biological environment. Microwave catalysis appears a promising method for soil remediation due to its fast and effective heat transfer, but it is challenging to prepare catalysts with good electromagnetic wave absorption and robust catalytic activity. In this study, atomically dispersed Fe on three‐dimensional...
Most organic semiconductors (OSCs) consist of conjugated skeletons with flexible peripheral chains. Their weak intermolecular interactions from dispersion and induction forces result in environmental susceptibilities and are unsuitable for many multifunctional applications where direct exposure to external environments is unavoidable, such as gas absorption, chemical sensing, and catalysis. To exploit...
Memristors are emerging as a rising star of new computing and information storage techniques. However, the practical applications are severely challenged by their instability toward harsh conditions, including high moisture, high temperatures, fire, ionizing irradiation, and mechanical bending. In this work, for the first time, lead‐free double perovskite Cs2AgBiBr6 is utilized for environmentally...
Conjugated coordination polymers have become an emerging category of redox‐active materials. Although recent studies heavily focus on the tailoring of metal centers in the complexes to achieve stable electrochemical performance, the effect on different substitutions of the bridging bonds has rarely been studied. An innovative tailoring strategy is presented toward the enhancement of the capacity storage...
Nitrogen dioxide (NO2) emission has severe impact on human health and the ecological environment and effective monitoring of NO2 requires the detection limit (limit of detection) of several parts‐per‐billion (ppb). All organic semiconductor‐based NO2 sensors fail to reach such a level. In this work, using an ion‐in‐conjugation inspired‐polymer (poly(3,3′‐diaminobenzidine‐squarine, noted as PDBS) as...
Recently, organic–inorganic hybrid perovskites (OIHP) are studied in memory devices, but ternary resistive memory with three states based on OIHP is not achieved yet. In this work, ternary resistive memory based on hybrid perovskite is achieved with a high device yield (75%), much higher than most organic ternary resistive memories. The pseudohalide‐induced 2D (CH3NH3)2PbI2(SCN)2 perovskite thin film...
Smart nanoparticles are increasingly important in a variety of applications such as cancer therapy. However, it is still a major challenge to develop light‐responsive nanoparticles that can maximize the potency of synergistic thermo‐chemotherapy under light irradiation. Here, spatially confined cyanine‐anchored silica nanochannels loaded with chemotherapeutic doxorubicin (CS‐DOX‐NCs) for light‐driven...
An organic thin‐film gas sensor based on squaraine detects ammonia as low as 40 ppb with impressive reversibility and stability. The resonance‐stabilized zwitterionic characteristics offer squaraines high affinity and sensitivity toward electron‐rich analytes without irreversible chemical binding, while the embedded squaric ring makes SA‐CH3 highly sensitive. The symmetric molecular geometry and good...
