Flexible integration spurs diverse applications in metal-organic frameworks (MOFs). However, current configurations suffer from the trade-off between MOF loadings and mechanical compliance. We report a wrinkled configuration of MOF thin films. We established an interfacial synthesis confined and controlled by a polymer topcoat and achieved multiple Turing motifs in the wrinkled thin films. These films have complete MOF surface coverage and exhibit strain tolerance up to 53.2%. The enhanced mechanical properties allow film transfer onto various substrates. We obtained membranes with large H 2 /CO 2 selectivity (41.2) and high H 2 permeance (8.46 × 10 3 gas permeation units), showcasing negligible defects after transfer. We also achieved soft humidity sensors on delicate electrodes by avoiding exposure to harsh MOF synthesis conditions. These results highlight the potential of wrinkled MOF thin films for plug-and-play integration.

具有可调谐图灵图案的皱纹金属有机框架薄膜，可实现柔韧集成


灵活的集成促进了金属有机框架（MOF）的多样化应用。然而，当前的配置面临 MOF 负载和机械顺应性之间的权衡。我们报告了 MOF 薄膜的皱纹结构。我们建立了由聚合物面漆限制和控制的界面合成，并在皱纹薄膜中实现了多个图灵图案。这些薄膜具有完整的 MOF 表面覆盖，应变耐受性高达 53.2%。增强的机械性能允许薄膜转移到各种基材上。我们获得了具有大H 2 /CO 2 选择性（41.2）和高H 2 渗透性（8.46 × 10 3 气体渗透单位）的膜，转移后的缺陷可以忽略不计。我们还通过避免暴露在恶劣的 MOF 合成条件下，在精密电极上实现了软湿度传感器。这些结果凸显了皱纹 MOF 薄膜在即插即用集成方面的潜力。
