Supramolecular steric hindrance designs make pyrene‐functionalized spiro[fluorene‐9,7′‐dibenzo[c,h]acridine]‐5′‐one (Py‐SFDBAO) assemble into 2D nanostructures that facilitate aqueous phase large‐area synthesis of high‐quality and uniform crystalline thin films. Thin‐film diodes using aqueous nanosheets as active layers exhibit a non‐volatile bistable electrical switching feature with ON/OFF ratios of 6.0 × 10 4 and photoswitching with conductive gains of 10 2 –10 3 . Organic nanosheets are potentially key components for eco‐friendly aqueous dispersed organic nano‐inks in the application of printed and flexible electronics.
