Abstract

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.
