Synthesis and Electroluminescent Properties of Soluble Poly(3,6-fluorene) and Its Copolymer
摘要:
Soluble poly(3,6-fluorene) and its copolymer were synthesized by nickel-catalyzed coupling. Poly(3,6-fluorene) exhibited the optical band gap of 3.6 eV, the emission maximum at 347 nm, and the HOMO level of -6.05 eV. These results confirm that 3,6-linkage is an effective way to get wide band gap conjugated polymers. Furthermore, its copolymer containing triarylamine moieties emits deep-blue light, which means that the adjustable blue light emission can be obtained from their copolymers via energy transfer.
