Strongly Correlated Alignment of Fluorinated 5, 11‐Bis (triethylgermylethynyl) anthradithiophene Crystallites in Solution‐Processed Field‐Effect Transistors
ChemPhysChem, 2014•Wiley Online Library
The crystallinity of an organic semiconductor film determines the efficiency of charge
transport in electronic devices. This report presents a micro‐to‐nanoscale investigation on
the crystal growth of fluorinated 5, 11‐bis (triethylgermylethynyl) anthradithiophene (diF‐
TEG‐ADT) and its implication for the electrical behavior of organic field‐effect transistors
(OFETs). diF‐TEG‐ADT exhibits remarkable self‐assembly through spin‐cast preparation,
with highly aligned edge‐on stacking creating a fast hole‐conducting channel for OFETs.
