摘要：
Provided is a polymeric fluorescent substance showing fluorescence in solid state, which has a specific carrier drift mobility, a specific repeating unit, and specific number-average molecular weight. The polymeric fluorescent substance is excellent in solubility to organic solvents, and has higher efficiency and longer lifetime in applying as a polymer LED.
