Abstract

Provided are semiconductors prepared from an enantiomerically enriched mixture of a nitrogen-functionalized rylene bis(dicarboximide) compound. Specifically, the enantiomerically enriched mixture has unexpected electron-transport efficiency compared to the racemate or either of the enantiomers in optically pure form.
