Abstract : Although materials with high third order susceptibilities demonstrate optical switching or limitation in response to critical input intensity, application in devices for sensor protection (to include that of the human eye) has not yet been brought to practicable fruition. Devices such as goggles require an optically clear carrier of high transparency and good mechanical properties for the NLO material. Our goals are directed toward development of such a material by incorporation of chi 3-active materials into a polymeric carrier which is strong and transparent. Although chi 3 properties do not require noncentrosymmetry, the NLO behavior frequently is enhanced by alignment which removes the symmetry element. In addition, the structural integrity of polymers is frequently improved by alignment. Thus, a central theme of our Phase I study is the alignment of the guest/host systems as a route to development of protective materials. Promising chi 3-active materials will be processed into films using polycarbonate (PC) relying on its requisite optical and mechanical properties as the host polymer. Three NLO-active components will be evaluated: (1) a tetrabenzoporphyrin (TBP), (2) a polyaniline (PANI), and (3) a sol complex. Thus a full range of both molecular and polymeric NLO-active substances will be surveyed in Phase 1.
