The conducting poly(3,4-disubstituted pyrroles) doped with organic electron acceptors

Takehira Kaneko; Nobuo Matsui; M. Kamiyama; Tomio Yagihara

Abstract The conducting films were prepared from a solution containing a soluble poly(4-methylpyrrole 3-carboxylate) and an organic electron acceptor. The principal acceptor studied here was tetracyanoethylene (TCNE). The solution was homogeneous, so that the conducting film was obtained directly from the solution cast on a glass plate or some substrates. The present films exhibited relatively high conductivity (≈ 10 4 ∼ 10 1 S/cm), which was dependent on quantity of TCNE added to the polymer solution and the alkyl-chain length of the esters.
