Rod-like ZIF-L was formed with the aid of PVP through a self-assembly mechanism. A fast phase transformation from irregular ZIF-L to rhombic dodecahedral ZIF-8 occurred once ethanol was used as the washing solvent due to its weak crystallinity and small size. ZIFs with different coordination modes, morphologies and sizes were obtained via this facile method.

棒状ZIF-L的形成机理以及从ZIF-L到ZIF-8的快速相变，其形态变化受聚乙烯吡咯烷酮和乙醇的控制†

棒状ZIF-L是在PVP的帮助下通过自组装机制形成的。一旦使用乙醇作为洗涤溶剂，由于其弱的结晶度和较小的尺寸，就会发生从不规则ZIF-L到菱形十二面体ZIF-8的快速相变。通过这种简便的方法可以获得具有不同配位模式，形态和大小的ZIF 。
