The present invention provides a thieno [3,2-b] indole-based polymer and an organic electroluminescent device in which the polymer is introduced into an organic film. The thieno [3,2-b] indole-based polymer is easy to prepare and exhibits blue luminescence properties, and the thieno [3,2-b] indole (thieno [3,2-b] indole) polymer is easy to prepare. The organic electroluminescent device employing an organic film using a 3,2-b] indole) -based polymer has improved color purity, efficiency and luminance characteristics. |
