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.
超分子空间位阻设计使得芘功能化螺[芴-9,7'-二苯并[c,h]吖啶]-5'-酮（Py-SFDBAO）组装成二维纳米结构，有利于在水相中大面积合成高质量和均匀的结晶薄膜。使用水性纳米片作为有源层的薄膜二极管具有非易失性双稳电开关特性，其导通/关断比为 6.0×10(4)，具有光开关功能，电导率增益为 10(2)-10(3)。有机纳米片有望成为环保型水性分散有机纳米油墨在印刷和柔性电子中的关键组成部分。
