Abstract

Porphyrinic metal-organic frameworks (MOFs) offer high surface areas and tunable catalytic and optoelectronic properties, making them versatile candidates for applications in phototherapy, drug delivery, photocatalysis, electronics, and energy storage. However, a key challenge for industrial integration is the rapid, cost-effective production of suitable sizes. This study introduces Zr(IV) alkoxides as metal precursors, achieving ultrafast (∼minutes) and high-yield (>90%) synthesis of three well-known Zr-based porphyrinic MOF nanocrystals: MOF-525, PCN-224, and PCN-222, each with distinct topologies. By adjusting linker-to-metal and modulator-to-metal ratios, we attain precise control over single-phase formation. Demonstrating alkoxides' potential, we synthesized nanosized PCN-224 at room temperature within seconds using a continuous multifluidic method. This advancement greatly simplifies porphyrinic MOF production, enabling broader industrial and scientific applications.

醇盐前驱体超快合成锆-卟啉骨架纳米晶。

卟啉金属有机框架（MOFs）具有高表面积和可调的催化和光电子性能，使其成为光疗、药物输送、光催化、电子和能量存储等领域的多功能候选材料。然而，工业一体化的一个关键挑战是快速、经济地生产合适尺寸的产品。本研究引入Zr（IV）烷氧化物作为金属前驱体，实现了三种众所周知的Zr基卟啉型MOF纳米晶体的超快（~分钟）和高产率（>90%）合成：MOF-525， PCN-224和PCN-222，每一种都具有不同的拓扑结构。通过调整连接器与金属的比率和调制器与金属的比率，我们可以精确控制单相地层。为了证明烷氧化物的潜力，我们使用连续多流体方法在室温下几秒钟内合成了纳米级PCN-224。这一进步极大地简化了卟啉类MOF的生产，实现了更广泛的工业和科学应用。
