Polymers from certain conjugated organic compounds

The invention relates to conjugated compounds of general formula (I) wherein X1 and X2 are, independently of one another, electron-withdrawing or electron-donating systems, and to a process for the preparation of these compounds. The invention also relates to any material which includes the compound...
