Abstract
A highly functional electroluminescent polymer which has a 9-fluoren-2-yl-2,7-fluorenyl unit and in which substituted fluorenyl groups are introduced to a 9-position of fluorene, and an electroluminescent device using the same. The electroluminescent polymer includes host monomers required to produce a highly efficient host material for blue, green, and red colors, and has high functionality, such as high solubility, thermal stability, and quantum efficiency.
