摘要：

Superquenching of conjugated polymers by viologen derivatives was discussed. Effect of hydrophobicity was studied. Results showed that the ionic quenchers enhance the aggregation of water-soluble conjugated polymers. It was also found that hydrophobicity of the quencher also plays an important role.
