Description
Three-dimensional Covalent Organic Frameworks (3D COFs) possess highly tunable porous structures that hold immense potential for advanced device applications. However, their integration into active nano- and microsystems is currently bottlenecked by conventional solvothermal synthesis methods. These traditional approaches require prolonged reaction times (>12 h) and typically yield unprocessable powders, preventing seamless device fabrication. To address the historical lack of preassembly mechanisms in 3D COF synthesis, we introduce a pioneering synthetic environment governed by precisely controlled diffusion. By eliminating turbulent mixing and fine-tuning the spatial reaction zone, we establish an unprecedented methodology that enables the rapid, one-pot synthesis of 3D COFs in under one minute. Crucially for active system integration, this diffusion-controlled approach directly yields self-standing 3D COF fibers on a centimeter scale. This breakthrough in material processability effectively bridges the gap between raw 3D COF synthesis and functional device manufacturing, offering a versatile, scalable pathway for their seamless integration and spatial patterning within next-generation nano- and microsystems.
