Abstract:
A polymeric fluorescent substance exhibiting fluorescence in the solid state, having a polystyrene reduced number-average molecular weight of 1×103 to 1×108, and comprising one or more repeating units of formula (1) and one or more repeating units of formula (8), —Ar1—(CR1═CR2)n— (1) —Ar2—(CR36═CR37)n— (8) wherein Ar1 represents a specific arylene or a divalent heterocyclic compound group, and Ar2 represent an arylene or a divalent heterocyclic compound group other than Ar1. By using the polymeric fluorescent substance, a high performance polymer LED can easily be obtained.
