Abstract

We synthesized two different polyurethanes containing methylsulfonyl benzothiazolyl azo chromophore (MS-polyurethane) and p-nitroazobenzene chromophore (NP-polyurethane) in the side chain by condensation polymerization respectively. The structural effect of the chromophore on the level and the induction rate of induced birefringence was investigated. Polarized absorption spectroscopy was employed to study the reorientation of azobenzene chromophore using two polymers. We also investigated the properties of optically induced birefringence in Polyurethane film by changing the wavelength (λ= 488 nm, 514 nm) of the linearly polarized excitation light.
