CONJUGATED POLYCARBAZOLE DERIVATIVES AND PROCESS FOR THE PREPARATION THEREOF

摘要

The invention relates to conjugated polycarbazole derivates comprising repeating or alternating units of the formula: (see fig I) wherein R is a linear or branched alkyl group containing 1 to 22 carbon atom s. The conjugated polycarbazole derivatives according to the invention hav e interesting optical and electrochemical properties which render them suitabl e for use in the manufacture of diverse electrical, optical and electro-optical devices
