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 × 104 and photoswitching with conductive gains of 102–103. Organic nanosheets are potentially key components for eco-friendly aqueous dispersed organic nano-inks in the application of printed and flexible electronics.
