The present invention provides a carbazole compound represented by the following formula (I):  wherein each Arindependently represents a substituted or unsubstituted monovalent aromatic group or an aromatic group containing a heteroring, and Rand each Rindependently represent a hydrogen atom, an alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group.

Carbazole compound, and polymer thereof

Provided are a thiophene-containing compound represented by the following formula (X-1), and an organic electroluminescent device that includes a pair of electrodes and an organic compound layer disposed therebetween. The organic compound layer includes a charge-transporting polyester having a repeating structure containing at least one structure selected from the structures represented by the following formulae (I-1) and (I-2) as its partial structure. In formula (X-1), Arrepresents a substituted or unsubstituted monovalent aromatic group; and Rto Reach independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; and n' is an integer of 1 to 5. 

The present invention provides a thiophene-containing compound represented by Formula (I) and a thiophene-containing compound polymer using the thiophene-containing compound. In Formula (I), Arrepresents a substituted or unsubstituted monovalent aromatic group; X represents a divalent straight-chain hydrocarbon group having 1 to 6 carbon atoms, a divalent branched-chain hydrocarbon group having 2 to 10 carbon atoms, or a substituted or unsubstituted divalent aromatic group; Rto Reach independently represent a hydrogen atom, an alkyl group, a cyano group, a halogen group, a substituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; 1 represents an integer from 1 to 5; and m and k each independently represent 0 or 1. 

Thiophene-containing compound and polymer thereof

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.
