Abstract

The condensation polymer derived from reaction between titanocene dichloride and 2-nitro-1,4-phenylenediamine was doped by mixing the polymer with different amounts of iodine. This bulk doping of the titanocene polyamine resulted in an increase in bulk conductivity from 10 to over 1,000 fold. Conductivity increased to a doping level of about 10 to 15% iodine. Conductivity decreased as the sample discs were heated returning to pre-doped levels after the samples were heated for eight minutes. It is believed that this decrease in conductivity is due to the surface evaporation of iodine as the samples were heated. MALDI MS and IR results are consistent with the formation of C-I compounds for doped materials.
