Irradiance and Temperature Dependence of Photo-Induced Orientation in Two Azobenzene-Based Polymers

Abstract

This paper concerns itself with photo-induced anisotropy in two azobenzene functionalized polymers. A simple physical model of the process which considers only three possible states of azo chromophores is proposed. This model predicts an equilibrium level of anisotropy which 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)-ETHYLazobenzene (pMEA) and poly4'-2-(METHACRYLOXY)ETHYLamino-4-nitroazobenzene (pDR1M).
