Abstract:
The nonlinear photomechanics and thermodynamics of azobenzene liquid crystal polymer networks is studied to quantify interactions between wavelength dependent molecular conformation changes that occur within a polymer network. The transfer of energy from light to liquid crystals to a polymer network strongly depends on the wavelength and polarization of light where trans or rod shaped azobenzene chromophores convert to a cis or kinked conformation and simultaneously may relax back to the trans state but in a different orientation. This behavior requires an understanding of the dynamic interactions between light and azobenzene molecules and thermodynamics of light-matter interactions. We investigate this behavior by quantifying transmission and absorption of electro-magnetic energy with stored energy within the solid material. This is conducted by introducing a set of optical order parameters coupled to photochemistry that evolve as a function of electro-magnetic radiation.
