Covalent organic frameworks (COFs), as an emerging subclass of crystalline porous materials, combine structural adaptability with tunable photophysical properties, making them highly promising for piezochromic applications. However, research in this specific area remains notably limited. Herein, a series of donor-acceptor structured two-dimensional covalent organic frameworks (2D COFs) exhibiting bright red emission was successfully synthesized, all of which demonstrate a pronounced red-shift spanning the red and near-infrared regions. Notably, Py-BO-COF shows the largest piezochromic shift of 187 nm with a high sensitivity of 44.52 nm GPa<sup>−1</sup>, significantly exceeding that of Py-BT-COF, TPE-BO-COF, and most reported COF/MOF systems. Remarkably, Py-BO-COF exhibits fully reversible and repeatable emission switching over multiple cycles, consistently maintaining excellent linearity without degradation. This combination of high sensitivity and outstanding reversibility positions Py-BO-COF as a promising candidate for high-performance piezochromic materials. <i>In situ</i> spectroscopic analyses and theoretical simulations further reveal that the variation in piezochromic rates among the COFs arises from differences in charge-transfer (CT) processes, while the pronounced red-shifts in Py-BO-COF is associated with reduced interlayer distance and enhanced coplanarity. This study systematically establishes the structure-property relationship in piezochromic 2D COFs, offering strategic guidance for designing highly sensitive and reversible pressure-responsive materials, thereby advancing the field of smart piezochromic systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"69 8","pages":"4626 - 4634"},"PeriodicalIF":7.7,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, achieving a high-yield bump array becomes challenging under high-density conditions. In this study, we innovatively use a photosensitive conductive polymer (PCP) to replace conventional metal bumps, serving as a new bonding material between Micro-LEDs and the driving substrate, which can be used to fabricate polymeric micro-bump arrays through well-established photolithography, elegantly bypassing the complex lift-off process in the preparation of traditional metal bumps, and yet keeping a low risk of short circuits.

The degradation mechanisms in scalable processing are dissected, highlighting the critical role of precursor ink design, where solute purity, ink aging, and solvent engineering collectively govern film uniformity and reproducibility. The exacerbation of intrinsic instabilities under scalable processing is analyzed through crystal and compositional design, defect generation and passivation, and ion migration in large-area devices.

In this work, aramid nanofiber/carbon nanotube (ANF/CNT) aerogel fibers, integrating passive thermal insulation and active solar heating, were prepared by wet-spinning and ambient-pressure drying (APD). The incorporation of CNT and Ca<sup>2+</sup> into ANF aerogel fibers generates abundant physical and chemical crosslinking points, strengthening the nanofiber network’s skeleton, and thereby reducing the structural collapse during APD with only 8.9% shrinkage. Thus, the synthesized ANF/CNT aerogel textiles demonstrated low thermal conductivity (33.8–40.4 mW/(m K)) and thermal insulation ability from −196 to 400 °C. More importantly, the photothermal effect of CNT enables active solar heating of aerogel fibers, effectively supplementing their thermal insulation, and allowing them to withstand extremely cold environments. In real tests, the synergistic effect of passive insulation and active heating improved the skin temperature by up to 5.9 °C, much higher than 1.6 °C obtained solely for passive insulation.
