Polyfluorenes are promising blue light emitting materials for their high efficiency and bright as emitting layer in polymeric light emitting devices (PLEDs). But blue-green or green light emitting with the maxima around530 ~550nm in PL and2.2~2.3eV in EL have been observed in the solid state film and PLED after an experimental run. The progress in recent years in the exploring mechanism of the low-energy gap emission
including the experimental evidences
theoretical calculations
and the methods to improve the blue light emitting stability
were reviewed in this article.
