Abstract Flexible resistive random‐access memory (RRAM) holds significant promise for data storage applications in the realms of smart healthcare and wearable devices. However, most research has focused primarily on development stretchable electrodes, frequently neglecting mechanical compatibility between functional layer electrode. Consequently, advancement intrinsically memristors presents a substantial challenge. Herein, glassy metal‐organic framework (MOF) film with wrinkle structure is integrated pre‐stretched electrode to fabricate memristors. These devices demonstrate an impressive switching ratio up 10 5 , bending radius limit mm, strain 20%, all while maintaining stable characteristics. Furthermore, conductive atomic force microscope (C‐AFM) ion beam (FIB) techniques reveal that effect governed by silver filament mechanism. This work successfully developed memristor, paving way application MOFs as layers flexible electronics. It expected inspire further design high‐performance, electronic technologies.

The modulation of cavity dimension is crucial for the realization versatile micro-/nanolasers, yet fabrication molecular crystals derived from high-orientation assembly mode molecules, limiting optical to a low-dimensional anisotropic topography with sharp corners and high thresholds. Here, we propose an innovative strategy achieve orientation engineering organic microcrystals flexibly modulating dimension. isotropic orientations generate different-dimensional microcavity structures (one-dimensional microbelts three-dimensional (3D) microspheres) distinct lasing actions. 3D microspheres perfect spherical morphology strong light confinement capability function as low-threshold whispering gallery-mode microlasers. Moreover, single-crystalline smooth lateral sides act Fabry-Pérot-mode lateral-cavity microlasers, which are formed between two faces microbelts. results offer useful insights into exploiting multidimensional micro-/nanolasers integrated photonic circuits.
