Abstract The photoluminescence (PL) peak of poly p-phenyl phenol (PPP) is at about 370-420nm excited by the light at 350nm. The absorption band edges and photon emitting peaks of the polymer are found the conjugated lengths dependent on molecular weight of polymer. In the transient luminescence measurement the lifetime of PL decay is determined to be 2.0ns which is supposed an evidence of polaron excitation recombination. The electroluminescence is observed with aluminum/PPP/indium- tinoxide cell.
