✦ Synopsis
A substantial enhancement of thermal stability, volatility, and electron affinity, switching the semiconducting behavior from p‐ to n‐type, is achieved by fluoroalkyl substitution of thiophene oligomers (see Figure). When this novel series is compared with the fluorine‐free analogues, trends in molecular packing, optical absorption, HOMO–LUMO gap, and π–π interactions are found to be strikingly similar.
