• 개요

  2-Bromo-9, 9’-spirobifluorene is a derivative of 9,9'-spirobifluorene. It is a quite useful blue light emitting material used in the organic light emitting diodes (OLEDs). It possesses high photoluminescence efficiency and good chemical stability. Moreover, It has high glass-transition temperature, excellent thermal stability and easy color tenability through introducing low band gap co-monomers.
