导电高聚物MP-PPV的ps吸收谱研究

Picosecond absorption spectroscopic studies on a conducting polymer MP-PPV

我们研究了在ps紫外脉冲激发下,导电高聚物MP-PPV溶液及薄膜的瞬态吸收谱。来自极化子和双极子的四个瞬态吸收带,在被稀释的MP-PPV溶液中被观察到,这些元激发的产生、迁移和衰变受不同实验条件的影响。

We have studied transient absorption of the conducting polymer MP-PPV in solution and film after picosecond UV pulse excitation. Four transient absorption bands have been observed in dilute solution and assigned to polarons and bipolarons. Generation, transport and decay of these elecmentary excitations are influenced by experimental conditions.
