    摘要： Provided is a polymeric fluorescent substance which emits a fluorescence in a solid state, which comprises the following repeating unit in an amount of 20 mol % or more based on the total amount of all repeating units, in the formula, X1 represents a group selected from the group consisting of —CR3═CR4—, —C≡C—, —SiR5R6—, —NR7—, —CO—, —CO—O—, —O—CO—, —SO2—, a carbon-carbon single bond, —O— and —S—. The polymeric fluorescent substance has strong fluorescence, and can be suitably used as a polymer LED and a dye for laser.
