Used as a surface modifier in organic electronics and semiconductor devices due to its strong affinity for metal oxides. Forms self-assembled monolayers (SAMs) on substrates like aluminum, indium tin oxide (ITO), and other metals, improving electron injection and reducing interfacial defects. Enhances performance and stability in organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and perovskite solar cells by tuning work function and promoting adhesion. Also applied in corrosion inhibition and hydrophobic coatings owing to its fluorinated tail, which provides water and oil repellency.
