(57) [Problem] A white electroluminescent polymer compound comprising a carbazole-based polymer compound having photoconductivity, photovoltaic properties, photorefractive properties, and electrical activity better than conventional dimeric carbazole. And an organic electroluminescent device using the same. SOLUTION: General formula 1: embedded image And a white electroluminescent polymer compound having a main chain containing a 3,3′-bicarbazole structure, and an organic electroluminescent device using the same. The polymer compound overcomes the limitations of existing polymer blend resins by introducing a 3,3′-bicarbazole structure in which the N, N ′ position is substituted into the main chain containing a ring structure. . |
