文摘
- •
Two blue light-emitting polymers with aromatic unit in side chain are synthesized.
- •
The incorporated aromatic units can induce the formation of PFO β-phase.
- •
Both luminous efficiency and color purity can be simultaneously improved.
- •
A peak luminous efficiency of 2.25 cd A−1 was obtained for PFO-SO.
