“…Fluorine imparts enhanced properties to polymeric materials targeted for high performance or extreme conditions such as those needed for protective coatings, optoelectronic thin films, biomedical devices, aerospace materials, gas-separation membranes, and fuel cell applications. [1][2][3] The growing organic electronics industry has long sought extremely durable, lightweight, and cheap optoelectronic devices (e.g., OLEDs, organic photovoltaics (OPVs), and organic field-effect transistors (OFETs)) with high luminance at low voltage, and high color purity. 4,5 Translating the organic light-emitting diode (OLED) performance of fragile organometallics (such as Alq3 by Kodak in 1987 6 ) into robust polymers with real macromolecular properties continues to be a ''holy grail'' for organic electronics.…”
