Ming-Xing Zhang and Dr. Guang-Jiu Zhao Modification of n-Type Organic Semiconductor Performance of Perylene Diimides by Substitution in Different Positions: Two-Dimensional π-Stacking and Hydrogen Bonding ChemSusChem 5
Let's twist the fork: Perylene diimides (PDIs) and its derivatives are active n-type semiconducting materials widely used in organic electronic devices. This work elucidates different influences on electron-transfer mobility by substitution of PDIs in three different positions (bay-, ortho- and imide-positions) with chlorine. A fork-like structure is reported to be responsible for the large electron mobility of octachloro-PDIs with a twisted system.
