- A solution processable polymer was synthesized, by incorporating pyrene groups into the backbone of the
polyaniline chain, and used as an emissive layer in an organic light emitting diode. The polyaniline base was
reacted with acid chloride of pyrene butyric acid to form pyrene-functionalized polyaniline chains. The source
of pyrene moiety was acid chloride of pyrene butyric acid. The formation of polymer from acid chloride of
pyrene butyric acid and polyaniline was confirmed by the FTIR and 1H-NMR spectroscopy. Differential
scanning calorimetry revealed high glass transition temperature of 210 oC. Due to the presence of pyrene
moieties in the backbone, the polyaniline synthesized in the present study is solution processable with light
emitting property. The photoluminescence spectrum of the polymer revealed that emission lies in the blue
region, with a peak at 475 nm. The light emitting device of this polymer exhibits the turn-on voltage of 15 V.
