Abstract
The conductivity of the polyamine derived from titanocene dichloride and 2-nitro-1,4-phenylenediamine increases to 101 to 103 fold when doped with iodine. Larger increases are found for the analogous polyamines except derived from zirconocene dichloride (increased 103–104 fold) and hafnocene dichloride (105–106 fold) and for certain other diamines. The conductivity of the product of titanocene dichloride and N-methyl-1,4-phenylenediamine increased 105 fold when doped. By comparison, conductivity increased only tenfold for the product from titanocene dichloride and chloro-1,4-phenylenediamine and less for the titanocene product with 1,4-phenylenediamine and methoxy-1,4-phenylenediamine and none for the product from dibutyltin dichloride and 2-nitro-1,4-phenylenediamine. Conductivity did not appreciably change when samples were exposed to the atmosphere for 21 h. MALDI MS and IR results are consistent with the formation of C–I compounds for doped materials.
