摘要：

This paper concerns itself with photoinduced anisotropy in two azobenzene-functionalized polymers. A simple physical model of the process that considers only three possible states of azo chromophores is proposed. This model predicts an equilibrium level of anisotropy that depends on the pump irradiance and temperature. Each of these influences is examined in turn, with experimental illustrations from the two polymers poly[4-[2(methacryloxy)-ethyl]-ethyl]azobenzene] (pMEA) and poly[4'-[[2-(methacryloxy)ethyl]-ethyl]a (pDRIM).
