Abstract This article reports the synthesis and characterization of a novel thermally crosslinkable hole-transporting poly (fluorene-co-triphenylamine)(PFO-TPA) by Suzuki coupling reaction, followed with its application in the fabrication of multilayer light-emitting diodes by wet processes. The thermal, photophysical, and electrochemical properties of PFO-TPA were investigated by differential scanning calorimeter, thermogravimetric ...
