No full textEffect of temperature and atmospheric environment on the photodegradation of some Disperse Red 1 type polymers
No full textInternational audienceThe photodegradation of the azobenzene chromophore DR1 {4-[N-ethyl-N-(2-hydroxyethyl)amino]-4'- nitroazobenzene]} incorporated as a side chain or as a guest in a poly(methyl) methacrylate host has been evaluated as a function of wavelength, temperature, and the atmospheric environment. The effects of these variables on the lifetime of DR1-based electro-optic devices is quantifie
Photodegradation of azobenzene nonlinear optical chromophores: the influence of structure and environment
No full textInternational audienceThe photodegradation of a variety of donor-acceptor-substituted azobenzene nonlinear optical chromophores has been studied. The variables examined that influence the rate of degradation include chromophore and host polymer structure, irradiation wavelength, temperature, and atmosphere
