Abstract
Current generation polystyrene-, polyacrylate-, and polyethylene-based5 materials are intrinsically limited in a designed functionalization level to a maximum of one chromophore molecule per repeat unit (in most cases, considerably less has been achieved) and to architectures having undesired residual chain mobility, as suggested by Tg data. This paper addresses several of these issues and describes the synthesis and characterization of a new class of highly functionalized SHG polymers derived from the robust, high-Tg (205-210°C) thermoplastic poly(2,6-dimethyl-1,4-phenylene oxide) (PPO). To better define the transparency characteristics of the subject films, the authors also report the fabrication of a waveguide. Preliminary waveguiding experiments were performed on several PPO-NPP films to better define their optical characteristics. A planar waveguide structure consisting of air/film/glass layers was used. The waveguide modes were excited with a He-Ne laser (0.633 μm) using prism-coupling techniques with SF6 glass (n = 1.797) prisms as the couplers. The refractive index of the films was determined from the coupling angles of various waveguide modes.
