One‐Pot Synthesis of Axially and Centrally Chiral A‐type Nanogrids

Comprehensive Summary A novel type of A‐type nanogrids (AGs) with axial and central chirality was synthesized via Friedel‐Crafts gridization of thiophenes and difluorenyl biaromatic derivatives, yielding 9%—30%. Additionally, the effect of stereoisomers of 1,1’‐binaphthyl difluorenols (BINDFOH) was investigated to demonstrate that R / S ‐BINDFOH is more advantageous for the synthesis of AGs than Mix‐BINDFOH. Furthermore, tests on OFET memory devices showed that AGs have a larger storage window, indicating potential for data storage applications.
