Abstract
The present invention relates to a thiophene-containing compound and a thiophene-containing compound polymer which are useful for organo-electronic devices such as electrophotographic photoreceptors (photosensitive elements), organic electroluminescent elements and organic transistors. More specifically, the invention relates to a thiophene-containing compound and a thiophene-containing compound polymer which are excellent in terms of both charge-transporting properties and luminous properties.
