ABSTRACT:
An electroluminescent polymer which has repeating units represented by formula (1) is obtained by polymerizing a bisfluorenylsilane compound which has specified substituent groups.In spite of the fact that this electroluminescent polymer is a π-σ conjugated type fluorene polymer, the deterioration in the color purity of EL caused by excimer formation is suppressed, so that the color purity of blue emitted light in particular is extremely high. This electroluminescent polymer is extremely useful as a light-emitting material in organic electroluminescent elements.
