摘要：

The reversible cis-trans photoisomerization of azobenzene derivatives is very sensitive to. the polarization of the pumping beam which induces birefringence and dichroism. Recently, we have demonstrated a new method for poling azo dye-containing polymers, at room temperature, by applying a d.c. electric field during the optical pumping process. Here, we present a model for the dynamics of the photoinduced modifications of the angular distribution of chromophores and we compare a guest-host system (Disperse Red 1 (DR1) in PMMA) and a PMMA-DR1 copolymer.
