Abstract

Appending high-β chromophores to glassy macromolecules represents an advance in NLO materials1 design in that chromophore number densities are greatly enhanced and structural disorientation/physical aging processes subsequent to cessation of electric field poling are impeded.2, 3 Further enhancements in the SHG (second harmonic generation) temporal stability of such materials can be achieved by effecting thermal cross-linking/vitrification of the matrix in concert with the poling process.2a, 4, 5Nevertheless, optimum architectural strategies for such cross-linking processes, either chemical or hydrogen hydrogen-bonding, have not been systematically addressed. We report here modifications of our previously investigated poly(p-hydroxystyrene)-N-(4-nitrophenyl)-(S)-prolinol (NPP-PHS) chromophore-functionalized polymer system, 2c, d which afford the first opportunity to probe SHG temporal stability as a function of cross-link/hydrogenbond location (I).
