Displays are basic building blocks of modern electronics 1,2. Integrating displays into textiles 17 offers exciting opportunities for smart electronic textiles-the ultimate form of wearables 18 poised to change the way we interact with electronic devices 3-6. Display textiles serve to bridge human-machine interactions 7-9 , offering for instance, a real-time communication tool for individuals with voice or speech disorders. Electronic textiles capable of communicating 10 , sensing 11,12 and supplying electricity 13,14 have been reported previously. However, textiles 22 with functional, large-area displays have not been achieved so far because obtaining small illuminating units that are both durable and easy to assemble over a wide area is challenging. Here, we report a 6 m (L) × 25 cm (W) display textile containing 5×10 5 electroluminescent (EL) units narrowly spaced to ~800 μm. Weaving conductive weft and luminescent warp fibres forms micron-scale EL units at the weft-warp contact points. Brightness between EL units deviates by < 6.3% and remains stable even when the textile is bent, stretched or pressed. We attribute this uniform and stable lighting to the smooth luminescent coating around the 2 warp fibres and homogenous electric field distribution at the contact points. Our display textile is flexible and breathable and withstands repeatable machine-washing, making them suitable for practical applications. We show an integrated textile system consisting of display, 32 keyboard and power supply can serve as a communication tool, which could potentially drive 33 the Internet of Things in various areas including healthcare. Our approach unifies the 34 fabrication and function of electronic devices with textiles, and we expect weaving fibre 35 materials to shape the next-generation electronics.

Near‐infrared piezochromic materials presenting fluorescence responses with clear color differences and good penetrability have important potential applications, but a few such organic compounds are developed. Twisted intramolecular charge transfer (TICT) emission is versatile in solutions, especially for preparing bio/chem‐sensing materials due to the excellent sensitivity of the emission to alterations in the external environment. By analogy, the solid‐state TICT‐emissive chromophores are probably excellent candidates for the environmentally responsive material. Herein, X‐shaped π architectures that exhibit solid‐state TICT emission are developed, and their luminescent chromism and bioimaging properties are investigated. Initially, the cruciform fluorophore exhibits anomalous aggregation‐enhanced emission (AEE) and dual emission due to the existence of a TICT state. Interestingly, TICT emission is observed even in the aggregated state because the spacious environment around the bulky triphenylamine allows for rotation. During the compression process, the TICT‐based fluorophore demonstrates deep‐red to near‐infrared piezochromic behavior with a remarkable redshift (162 nm) and high sensitivity (15.1 nm GPa−1). The bioimaging performance of the TICT‐emissive dye suggests its potential utility as a fluorescent probe for biological applications.

The design and engineering of high-performance antimicrobial agents is critical for combating antibiotic resistance. In the present study, a rapid and broad-spectrum bactericidal agent is developed based on nanocomposites consisting of cobalt-doped zinc oxide (CoZnO) nanoparticles and MoS 2 nanosheets. The CoZnO/MoS 2 nanocomposites are prepared by a facile chemical precipitation method at controlled CoZnO and MoS 2 feeds. Scanning and transmission electron microscopic measurements show that CoZnO nanoparticles (ca. 10 nm in diameter) are clustered on the MoS 2 nanosheet surface, which facilitates the charge separation of the photo-generated electron−hole pairs, leading to enhanced photodynamic antimicrobial activity. Antibacterial assays in the dark show that the CoZnO/MoS 2 nanocomposite prepared at 30 μg of MoS 2 feed (CoZnO/MoS 2 -30) exhibits the best performance among a series of samples, with minimum inhibitory concentrations of 0.25, 0.8, and 1.8 mg mL −1 toward the Gram-negative bacterium Escherichia coli, Grampositive bacterium Staphylococcus aureus and fungus Aspergillus flavus, respectively. The antibacterial performance is markedly enhanced under photoirradiation, where 94.0% inactivation of E. coli is achieved with 20 μg mL −1 CoZnO/MoS 2 -30 nanocomposite under photoirradiation (15 W, 360 nm) for 5 min. The high antibacterial activity can be ascribed to peroxidase-like photocatalytic activity that is conducive to the generation of reactive oxygen species, as evidenced in transmission electron microscopy, electron spin resonance, and intracellular glutathione oxidation measurements. The results of the present study highlight the significance of CoZnO/MoS 2 nanocomposites as potent photodynamic antibacterial agents.
