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.
