ELECTROLUMINESCENT POLYMER, BIS-FLUORENYLSILANE COMPOUND AND ORGANIC EL ELEMENT |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a novelπ-σconjugate polymer especially having a high degree of color purity of blue light emission suppressed in reduction of the degree of color purity of EL caused by formation of an excimer in spite of aπ-σconjugate fluoren-based polymer. SOLUTION: The electroluminescent polymer has a repeating unit expressed by formula (1), wherein R<SP>1</SP>, R<SP>2</SP>, R<SP>5</SP>and R<SP>6</SP>express each H or a substituent; R<SP>3</SP>and R<SP>4</SP>expresses each independently an aryl or an alkyl; q expresses 1 or 2.
