Surface Doping Effect on the Optoelectronic Properties of Tetrachloro-Substituted Chiral Perylene Diimide Supramolecular Nanowires

In nature, chirality displays itself in diverse forms and on various hierarchical scales. Among the various types of chirality, supramolecular chirality is of particular interest due to its ability to amplify and induce chirality, which aids in understanding the fundamental principles of chirality transfer and is also suitable for chirality applications at the macroscopic scale. Herein, we report the synthesis of a novel chiral organic semiconductor 2,9-di(hexan-2-yl)anthra[2,1,9-def:6,5,10- d ′ e ′ f ′]diisoquinoline-1,3,8,10 (2 H, 9 H )-tetraone (ClCPDI-C6) and its self-assembly into supramolecular nanowires (NWs). The chirality of the NWs was successfully transferred via intra- and inter-molecular interactions from the chiral pendant to the perylene diimide (PDI) core after self-assembly. Upon exposing the organic NWs to phenylhydrazine dopant vapor, the average mobility of the NW tra…
