摘要：

The complex dielectric constants of several pi-conjugated materials were measured, and generalized Langevin equation was used to analyze the dielectric behavior in the frequency domain. From the results of the fitting the experimental data using the generalized Langevin equation, we suggest that the charge carriers are electrically screened by the neighboring charges through the structural relaxation, and the carriers are not interact each other. We confirmed that the generalized Langevin equation offers a very good approach to analyze and understand the transport properties of charge carriers in pi-conjugated materials.
