| Abstract: | A novel monomer derived from dibromocarbazole with N-grafted with Ir complex by a long alkyl side chain was synthesized. Based on this new monomer, a series of poly(fluorene-alt-carbazole)s which tethered red light-emitting Ir complex as emitting center were synthesized with Suzuki polycondensation. The polymer light-emitting diodes with structure of ITO/PEDOT∶PSS/PVK/Copolymer/Ba/Al were prepared based on the resulted copolymers. The copolymer PFCzIrNiq-1 exhibits maximal quantum efficiency of 0.23% at 9.4 mA/cm2. The peak emission of the resulted copolymers was at 680 nm, which was among the reported deepest iridium containing red-light-emitting electrophosphorescent polymers. |
