Paper Abstract

A special class of thermally stable poly(arylene ether) phosphine oxide polymers is being investigated for second-order nonlinear optical applications because of their high glass transition temperatures (> 200 degree(s)C). These polymers also have strong hydrogen bonding sites that can interact with the chromophores which may improve the temporal stability of chromophore orientation following poling. This work describes the polymer physics including structure/property relationships; in particular, the chromophore/polymer interactions and polymer backbone structures that influence the thermal and temporal stability of chromophore orientation in these polymer matrices. Second harmonic generation is sensitive to local changes in the polymer microenvironment and thus is an excellent technique for probing chromophore orientational dynamics during and following poling and the effect of dopant/polymer interactions on the temporal stability. Dielectric relaxation is employed to examine the intermolecular cooperativity and segmental relaxation behavior arising from different polymer backbone structures and steric effects. It is critical to understand how structure/property relationships affect the chromophore orientational dynamics and polymer relaxation in these polymers so that one can better tailor materials for nonlinear optical device applications.
