Ortho-diaminobenzene (ODB), Ortho-aminophenol (OAP) can be easily electropolymerized in acid aqueous solution, form continouus and adherent films. The polymer are 1,4-para position coupling. When pH<4, PODB is electroactive, its redox reaction which leads to the electrochromic behavior is concerned with H~+ ions. The electrode potentials of PODB, POAP behave Nernstian response vs. pH values from pH=4—10, electrode coefficience are 59mV/pH and 57mV/pH respectively. The Polymer H~+ ion selective electrode have realtively short respones time (less than 3 min.), good selectivity, reproductivity and stability. PODB, POAP are able to form complexes with transtion-metal ions Ni~(2+) and Co~(2+). The polymercomplex film show very stable cyclic voltametric behavior in alkaline media, the metal ions in film can be exchanced by H+ ion. —NH_2 group in PODB electrode can be remodified o introduce the quinone/hydroquinone functional group.
