Metal-organic frameworks (MOFs) are an emerging kind of laser material, yet they remain a challenge in the controlled fabrication of crystal nanostructures with desired morphology for tuning their optical microcavities. Herein, the shape-engineering of pure MOF microlasers was demonstrated based on the coordination-mode-tailored method. The one-dimensional (1D) microwires and 2D microplates were selectively fabricated through changing the HCl concentration to tailor the coordination modes. Both the single-crystalline microwires and microplates with strong optical confinement functioned as low-threshold MOF microlasers. Moreover, distinct lasing behaviors of 1D and 2D MOF microcrystals confirm a typical shape-dependent microcavity effect: 1D microwires serve as Fabry-Pérot (FP) resonators, and 2D microplates lead to the whispering-gallery-mode (WGM) microcavities. These results provide a special pathway for the exploitation of MOF-based micro/nanolasers with on-demand functions.

具有可控腔体形状的纯金属有机框架微激光器。
金属有机框架（MOF）是一种新兴的激光材料，但在可控制造具有所需形态以调节其光学微腔的晶体纳米结构的过程中，它们仍然是一个挑战。在此，基于协调模式量身定制的方法演示了纯MOF微激光器的形状工程。通过改变HCl浓度以适应配位模式，选择性地制造了一维（1D）微丝和2D微孔板。具有强光学限制的单晶微丝和微板都可以用作低阈值MOF微激光。此外，一维和二维MOF微晶的不同激光行为证实了典型的形状依赖性微腔效应：一维微线充当Fabry-Pérot（FP）谐振器，和2D微孔板导致了耳语画廊模式（WGM）微腔。这些结果为利用具有按需功能的基于MOF的微型/纳米激光器提供了一条特殊的途径。
