2- or 2,3-substituted 5,6,11,12-tetrathiotetracene and 5,6,11,12-tetraselenotetracene

摘要

2- or 2,3-substituted 5,6,11,12-tetraseleneotetracene or -tetrathiotetracene of the formula <IMAGE> in which X is S or Se, R is alkoxy, hydroxyalkoxy, aryloxy, cycloalkoxy, aralkoxy, -OH, -NH2, -Cl, -Br or substituted amino and Y is hydrogen or -COR. The compounds can be bonded as side groups to polymers. The polymers and the compounds combine with electron acceptors to form charge transfer complexes which can be used as electrically conductive layers.
