5-amino quinoline AQ was chemically oxidized in NH4 2S2O8/HCI system, whose structure was identified by UV-vis, FTIR, 1HNMR and 13CNMR analysis. Spectral analysis results indicated the formation of phenazine like units in the oxidation product and C3, C6, C8 positions of quinoline ring were suggested as a possible polymerization sites. Size exclusion chromatography indicated the oxidation product OAQ consisted of oligomeric units 1200 g/mol . OAQ was thermally stable and half of its mass was decomposed at 1000°C.
