Electrochemical and electric properties of vacuum-deposited poly(arylene)s: Electrochemical activity, diode, and electroluminescence

Journal Article · · Journal of Physical Chemistry

Vacuum-deposited thin films of poly(arylene)s [poly(p-phenylene), poly(thiophene-2,5-diyl) (PTh), poly(pyridine-2,5-diyl), and poly(2,2{prime}-bipyridine-5,5{prime}-diyl)] are electrochemically active, giving rise to doping and undoping peaks at essentially the same positions as those of original poly(arylene)s. Al/vacuum-deposited PTh/Au and Al/vacuum-deposited PTh/ITO electric junctions show rectification of electric current, which is accounted for by assuming the presence of a Schottky barrier between Al and PTh. The Al/vacuum-deposited PTh/ITO junction emits light at an applied voltage of 15 V. 9 refs., 4 figs., 1 tab.
