New poly (arylenevinylene) derivatives composed of biphenyl or terphenyl units in the main chain and fluorene pendant groups are synthesized by Yamamoto coupling reaction or Suzuki coupling reaction. The obtained polymers showed high color pure blue emission due to controlled conjugation length and inhibited intermolecular interaction as well as high solubility and good thermal stability.
