Metallated tetraazannulene (TAA) compounds were prepared and their electrochemical behavior determined as paraffin pellets inserted in a rotating disk electrode. Cobalt TAA, which had been heat treated at 600/sup 0/C for one hour, was observed to be the most active compared to iron, manganese and nickel TAAs and to nickel chloro-, dichloro- and nitro- TAA analogues. Cobalt TAA was shown to be as active on a weight percent basis as platinum in catalyzing the oxygen dissolution reaction in oxygen saturated concentrated phosphoric acid at room temperature. Cobalt TAA has been functionalized via a Mannich reaction and will be bonded directly to bromoacylated Vulcan XC-72. The activity and the stability of this bonded electrode material will be determined in the next quarter.
